On this weeks' Desk of Ladyada - we got a mess of prototypes including our Feather M4 Adalogger. We found a few mistakes, we'll chat about them so you can learn from us! We also got a flippy-floppy sensor Stemma QT board for the VEML7700, which comes in two reel flavors. pt has some hacker tunez to show off, and we'll unbox the new UNO MINI Limited Edition! The Great Search - USB to Serial converter chips https://www.digikey.com/short/z7bn9vpb A long time ago, in a galaxy far away, there were computers that came with DE-9 serial ports that would let you read/write 8-bit serial data on two lines. Those days are gone, now we have USB only. Many modern chips have a built in USB native peripheral so you can connect to a computer, but there's still lots of chips that don't! In that case you'll want a converter chip. Lets see what is available in the market and some things to watch out for when spec'ing them. #adafruit #arduino #deskofladyada Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI is easy-peesy-lemon-squeezy, the simplest way to add LTE cellular data connectivity to your product or project with Blues Wireless Notecard Cellular Modem System-on-Module (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecard-cellular-modem-som). These M2 cards come with 4 different cellular module types for global coverage on the LTE Cat 1 or Cat 1M (with backup CDMA and GPRS options). Each card slides into one of many different add-on boards that make connectivity to a Feather or Raspberry Pi foolproof. Blues Wireless' Notecard is a tiny 30 mm x 35 mm SoM device-to-cloud data pump. A Notecard purchase includes 500 MB of data that is usable over 10 years with the ability to top-up as needed. Connectivity is globally available in 136+ countries. The Notecard features an m.2 connector for embedding the user's board. As an embeddable SoM, the Notecard can be used with any microcontroller (MCU) for greenfield and retrofit projects using the user's design or one of Blues Wireless' custom-designed Notecarriers. With two lines of code, users can send data to the cloud in minutes without complex device registration or provisioning required. With a powerful JSON-based API, the Notecard can be programmed over USB or controlled from the preferred MCU or single-board computer (SBC) using one of Blues Wireless' open-source firmware libraries. Connect from the preferred host to the Notecard using Serial or I2C. The Notecard is designed to work with a cloud service for ingesting and processing device data. Notehub.io provides secure device connectivity, project, and fleet management, as well as simple routing to third-party cloud services. Alternatively, the user can host their device service based on Blues Wireless' open-source reference implementation. The Notecards use Quectel cellular modules, which are low cost and have been used for many years so they're very reliable. Depending on your location, you may not have LTE coverage yet (or LTE Cat M/M1) so do check your coverage maps and rollout plans - there's versions with GPRS (2G) and CDMA (3G) backup capabilities. The cellular plan itself is handled by Blues and is handled by AT&T, so no external SIM is required - although there is a insert spot for one if desired. Each module is bundled with a 10 year, 500MB cellular plan, which can be customized if needed. 500MB doesn't sound like a lot, but if you're using MQTT for sending data reports, where each packet is only a couple-hundred bytes max, it will last a long time. Check AT&T's coverage map to know which module you'll need to use for your area (https://www.att.com/maps/wireless-coverage.html) We particularly like the M.2 module design idea - it makes insertion very easy and doesn't allow for flipped boards or bent pins. Swapping out different modules can be done in a post-manufacturing step or as an add-on upgrade situation. It also means as cellular networks are upgraded and retired (which happens every 5~10 years!) the module can be changed over. If you need to source an M2 connector - Digi-Key has tons of those in stock too (https://www.digikey.com/short/zn1q8z), just make sure you get E-key type. These contacts are under a dollar a piece and come on tape-and-reel for easy pick and placing. The modules are designed for end-use cases. While prototyping you may want to use their handy "Notecarrier" breakout boards (https://www.digikey.com/en/product-highlight/b/blues-wireless/notecarrier). Each one can use any of the Notecards, so just mix and match as desired. There are ones for battery usage, Raspberry Pi HAT, and Feather breakout. (https://blues.io/products/notecarrier/) And best of all, all of the Blues Wireless Notecards and carriers are in stock right now at Digi-Key! (https://www.digikey.com/en/supplier-centers/blues-wireless) Pick up any combo you need to start prototyping your design immediately. You can get started with Blues' tutorials and code snippets (https://github.com/blues) - they promise you'll be sending data in under 30 minutes. Order today and you can be sending data over cellular by tomorrow morning. See on DigiKey.com at https://www.youtube.com/watch?v=kixNa2tLTLU

We had a nice long weekend with tasty food, hanging out with friends, and doing electronics! one thing we got around to finally was finishing a QT Py that is based on the ESP32-S2. Yeah this is many months old but we also wanted to wait till we could get the version of the chip with PSRAM built in. We're doing Arduino & CircuitPython tests now. Design is ready to go with a nice silkscreen :) The Great Search - uFL connector https://www.digikey.com/short/m55nzw3d For our QT Py board, we're starting with a mini 2.4 GHz antenna - but we know some folks will want better range than what this lil ceramic antenna can do. For them, we'll make a version with a uFL connector. These are a very low cost, but universally-used connector for RF signals. They're also easy to find on Digi-Key! #adafruit #deskofladyada #thegreatsearch Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This ESP32-S2 QT Py is so smol i just wannna pinch its lil cheeks! on the back is and ESP32-S2 with 4 MB Flash and 2MB PSRAM all stuffed inside this QFN chip. we verified Arduino works last night. So today we've been testing out CircuitPython support. Here's an Adafruit IO demo that sends sensor data from plug-n-play QT boards over MQTT to a dashboard. this demo has been runnin all day flawlessly. Just a few more tweaks to the design and silkscreen before we send off the PCBs - what color should we make this board? :) oh and...don't forget, we've got 20% everything in the feather category at adafruit.com/feather AND when you order 99$ or more, you get a FREE PINK FEATHER RP2040! https://www.adafruit.com/product/5299 #esp32 #adafruit #qtpy Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

This week's EYE ON NPI knows where it's been and where its goin'! We reckon you'll love the ST Teseo-VIC3DA and Automotive GNSS Dead-Reckoning Module and Eval Kit (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/teseo-vic3da-automotive-gnss-dead-reckoning-module), a technology that improves on GPS/GNSS by adding an IMU and odometer to help determine location in places where GPS signal is unable to reach such as tunnels and canyons. We've covered GPS (https://en.wikipedia.org/wiki/Global_Positioning_System) modules before on EYE ON NPI - they're many-decades-old technology that uses a satellite constellation to calculate 3D location on Earth with ~10 meter precision. They're great for use with cars or trucks because GPS works anywhere on the planet, and when combined with digital maps can easily calculate instructions, arrival time and recommended routes. However, GPS has a few things that it can't do. Most important is it cannot work at all if there's no clear view of the sky. One needs to constantly be receiving GPS data from 3+ satellites in order to determine location. So, if you're in tunnel or in a city-made canyon (http://wikimapia.org/6909209/Canyon-of-Heroes), or if there's RF shielding or interference, you simply 'drop off' the planet. Super awkward! For those situations, some companies or technologies can take advantage of "WiFi Assisted GPS" (https://link.springer.com/chapter/10.1007/978-3-642-13618-4_14) this is where a secondary base station, or WiFi signal names, can be used to help locate during low-visibility. This works particularly well in cities, of course, where there's a high density of AP names that don't change. But it's still pretty useless in a tunnel or outside a city center. There's also RTK, (https://blog.adafruit.com/2020/06/08/eye-on-npi-u-blox-c099-f9p-application-board-for-zed-f9p-gnss-rtk-module-eyeonnpi-adafruit-digikey-digikey-ublox/) which is awesome for increased precision and accuracy - but that requires a base station within a couple-hundred meters, and another transmission link on every device, so while it's used for some agricultural robotics, it's not always possible to implement (but it is worth investigating if you can control the environment where you're using GNSS.) So, finally we come to dead-reckoning techniques(https://en.wikipedia.org/wiki/Dead_reckoning). These work in an intuitive way: if you know where you last were and you count the number of steps and direction which you're going, then in theory you should be able to determine your exact location. Now, historically this technique has been used with boats and planes and hiking - in fact you probably learned it in scout camp. (https://en.wikipedia.org/wiki/Dead_reckoning#/media/File:CYA_Coastal_Navigation_With_Dead_Reckoning_2.jpg) And, while in theory it should be a perfect way to determine location, the implementation makes a massive difference on how usable the end product is. A slight error in direction angle makes for more and more drift error in the final result - and as humans struggle to calculate direction, it's better than nothing but not necessarily trustworthy without having reference checkpoints on a map. For this module, ST has worked on how to make it easy as possible to implement dead reckoning into your robot, with all the fixin's. First up, you're getting multi-constellation support. So not only American GPS, but also Europe's Galileo, Russia's Glonass, Japan's QZSS, and China's BeiDou systems. So if you can't get data from one constellation, you can use another. Next up, there's an internal 6-DoF sensor that is used as a tilt-compensated compass that will determine direction precisely. (GPS modules do give 'heading' but its just based on the last few locations). Next you need to calculate 'steps' - that's done with an odometer input. That pin is connected to a simple rotation-count sensor and direction sensor that will let the chip know how many ticks have passed since the last known fix. You can also send the odometer data over NMEA commands, btw. Finally, the module can combine this in the TESEO firmware to give you a fast (30 Hz) updated location! Usually this calculation stuff is the hardest part of doing dead reckoning so its really cool to see this all in one ST makes a very snazzy EVB-VIC3DA dev kit in an aluminum box and everything, (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) with ports and power supplies and LEDs so you can immediately toss it into your robot without any soldering or board layout required. The ST Dead-Reckoning GNSS modules TESEO-VIC3D (https://www.digikey.com/en/products/detail/stmicroelectronics/TESEO-VIC3DA/15276424), and EVB-VIC3DA eval boards (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) are in stock right now, for i

OK we're going to be fabbin the KB2040 board tomorrow! Yay PCBs arrived and we've got all the parts. Last thing I have to do for the team is hand off the tester. Over the weekend I've been doing a few testers over and it started getting annoying how much copypasta we have in our testers. So I wrote a Testbed library that sort of encapsulates a lot of the common code that is reused over and over.

This week's EYE ON NPI is clicky-clacky with Johnson Electric’s range of linear DC solenoids (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids) in various sizes and voltage ratings. Solenoids are a nifty type of motion control element - most folks think of motors or servos when thinking about motion control (and Johnson Electric does make motors too) but motors and servos are best used for rotation motion. You can convert them to linear motion but usually you need to gear them down a lot to get a reasonable torque - force conversion. Some use a rack-and-pinion mechanism (https://learn.adafruit.com/rack-and-pinion-bot/overview) or a drive/lead screw (https://en.wikipedia.org/wiki/Leadscrew). Solenoids provide a very easy to create a short but powerful linear force that is either on or off - you can't really be 'in the middle' of a solenoid actuation. Solenoids all work in the same basic way: there's a toroidal coil of copper that forms an electromagnet. (https://en.wikipedia.org/wiki/Solenoid) As current is passed through the coil, it pulls the ferrous slug into the coil with near-instant force. When the power is released, the electromagnet de-powers and the slug can move freely. In this sense, all solenoids are pull-type. Sometimes, there's a return-spring that will pull the slug out to 'reset it' - these are push-pull type (https://www.adafruit.com/product/413) - but most solenoids, including these from Johnson, don't have the spring. Usually, whatever the solenoid is installed in provides the return pressure. Most solenoids we've seen are rectangular style, which tend to be sort of 'candy bar' shaped. The Johnson solenoids are more 'pancake style' - with a flatter and wider design that has less requirements on depth. (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids) Johnson makes a couple dozen of different solenoids with different voltages and sizes, we picked up two and one was about the size of a grape and the other the size of an orange. Common voltage ratings are 12V and 24V - the amount of current will vary with voltage since you still need the same amount of power per coil size. Usually the voltage is whatever the equipment is set up to provide. Note that solenoids require a lot of current, many amps whenever activating! Thankfully the power does not have to be very clean, so you can have a separate regulated supply just for your motion control. Finally, the Johnson Electric YouTube channel has a cool series of videos called "Interviews with Old Timers" where they interview employees that have been there for 50+ years, to hear what it was like when Hong Kong was first beginning to do manufacturing. (https://www.youtube.com/watch?v=JyzoR-XtR6M) There's some great historical information in there, we had a lot of fun watching them and looking at the old photos. Digi-Key stocks a full range of compact solenoids from Johnson Electric available for immediate shipment. (https://www.digikey.com/en/product-highlight/j/johnson-electric/linear-dc-solenoids) Be sure to check the datasheets for the specs and sizes, as there's quite a range in size/voltage/actuation force! We picked up 2024-1026-ND, a chunky 12V one (https://www.digikey.com/short/40dmhdhj), as seen in the EYE ON NPI video, it's a real beast. Whatever size you need, if you order from Digi-Key today , you can be electro-magnetting by tomorrow afternoon. See on DigiKey.com at https://www.digikey.com/short/40dmhdhj
