Let's put together some breakout boards. This is a breakout for a round-rect 1.69" TFT. It's not the best time to be working on TFTs, given the shortage, but we wanted to wrap this one up anyways. We can use our little hot plate even though the PCB is larger, when we get to peak temp we just sorta move it around to get even-er heat. http://adafruit.com/minihotplate #adafruit #minihotplate #timelapse 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/ -----------------------------------------

These rotary encoder user-interface elements remind us a lot of very old iPods (before it was all touch wheel interface). The middle wheel is a rotary encoder, and there's 5 buttons in addition (up down left right and center). We made a breakout to test the footprint and whipped up a little demo - the Feather reads the buttons and encoder and light up the attached NeoPixel ring to match. So far so good! #adafruit #ipod #scrollwheel 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/ -----------------------------------------

A lot of folks like using Adafruit parts for their Keeb builds - but with the itsybitsy not being pin-compatible with the pro micro pinout, it really wasnt very easy without some sort of adapter plate. now we're seeing lots of people use circuitpython for keebs, which is awesome! why not try our hands at spinning up a pro-micro-compatible RP2040 board? the RP2040 is plenty powerful, low cost and makes for an excellent keeb driver chip. we tried to mix together the things we liked most about the sparkfun pro micro rp2040 (Qwiic/QT I2C port on the end, so good!) the Elite-C (castellated pads & pins for D+ and D-!) and our existing 2040 boards (boot button can be used for user, 8MB QSPI flash, onboard NeoPixel, jumper for skipping the diode/fuse for high power RGB LEDs or USB hosting). we even got it to all fit on a 2 layer PCB with 7/7 routing - just needed to make the smallest caps and resistors 0402. ground plane didnt suffer too much either - take a look!

We did a bunch of lil things this week, let's check them out: We designed a Kee Boar with the RP2040, based on the Pro Micro pinout but with some cute extras. Our snap-apart ortho keeb breakout PCBs arrived, as did our RP2040 macro-pad PCBs. We also tested our Zippy click-wheel breakout and are looking for a replacement chip for seesaw (that we can get in stock!)

Open source stories - Supporting MicroPython - ASK AN ENGINEER clip https://blog.adafruit.com/2021/04/29/happy-8th-birthday-micropython-micropython-micropython-and-adafruit-sponsoring-join-in/ We celebrated MicroPython’s previous birthdays, last year in NYC we were dealing with shutdowns, death, sickness, and more – so we did not get a chance to do a post. But with a new year and 2021 going in the right direction, we are making some noise about the 8th birthday in all the ways we can! Happy Birthday! We have stocked the official PyBoards from Damien, made direct donations to Micropython to support Damien’s work, make and share contributions, based on CircuitPython core on MicroPython and NOW with GitHub sponsors, we did a $5k sponsorship. Their goal is $5k a month in sponsors, so 1 full month is on us. We hope other companies and orgs that use MicroPython will consider doing a monthly or one-time as well. Companies / orgs can now sponsor, so this was Adafruit sponsoring. #adafruit #micropython #circuitpython

This week's EYE on NPI is one I've personally got an EYE on for a few months: the TI BQ25792 I2C Controlled, 1-4 Cell, 5-A Buck-Boost Battery Charger. This luxurious charger caught my eye a few months ago and now it's available for purchase and I'm really excited about it. This chip does everything you could ever want from a battery charger. We showed off a charger chip last week that was designed specifically for ultra-low current and voltages - great for TEC's or small solar cells. But what if you want HUGE charging capabilities? The TI BQ25792 has you covered, no matter your application. First great thing - support for any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries - if there's more batteries they are wired in series. But there's lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of em, and you can configure the battery pack size using a simple resistor on the PROG port. Second great thing - support for just about any voltage power supply input. Once you set the battery size, the output charging voltage has to be 4.2V-per-cell. Normally that means that if you're charging a 1S battery, you'd want a 5V power supply (4.2V plus some headroom). For 2S you want 9V to 12V, etc. Sometimes you'll see buck or boost chargers that let you have a lower or higher voltage. This chip is a buck-boost so you can have anything from 3.6V to 25V input and it will do the right thing to get you the voltage you need to charge the battery pack you have. There's some efficiency-loss on conversion, but much less than a linear supply and you don't have to worry about needing the exact-right power adapter or USB power supply. (https://e2e.ti.com/blogs_/b/powerhouse/posts/universal-and-fast-charging-a-future-trend-for-battery-powered-applications) OK we've done the output, we've done the input. Now lets look at the creamy middle: This charger has our favorite TI-capability: VINDPM and IINDPM - the ability to track the input voltage to make sure it is not drooping from over-draw. Say you have a battery, you want to charge it at 2A, but the wall adapter maxes out at 1A - you don't want the voltage to collapse on you, it's better to charge slowly at 1A than not at all at 2A. VINDPM/IINDPM auto-monitors the voltage and if it starts dropping, it will reduce the current draw. There's also ICO, which attempts to find the max-power-point for the power adapter, which may not be the exact same thing since there's different buck-boost efficiencies at different voltages. For when you're using USB for power, the charger can auto-detect the 'Apple-style' resistors used to set the max-draw current available. (In theory, we acknowledge it's probably better to just VINDPM/IINDPM when possible but we figure it's also polite to stick to the max-current-draw set by the chargers. Finally, there is an "OTG" mode where the converter 'turns around' and can be a buck-boost that runs off the battery to charge another device. Really a wonderful chip with a lot of capabilities and looks like no matter what it is you're trying to charge or power! I'm ordering some BQ25792 today for a new design I'm working on. From the looks of this datasheet, TI really stepped it up here (pun intended!) to make a battery charger everyone will love. Check out TI's video for a lot more details (https://www.youtube.com/watch?v=Wjk5YWrt8Ww) The BQ25792 is stock right now, for immediate shipment from Digi-Key (https://www.digikey.com/en/products/detail/texas-instruments/BQ25792RQMR/13577777) See on Digi-Key at https://www.digikey.com/short/3q2mnt5t

We noticed a few synth-makers getting worried about not being about to source TL074 quad op-amps! https://twitter.com/theavalkyrie/status/1381800012162666497 https://twitter.com/otdispace/status/1382920010042081283 We thought we'd spend this Great Search looking at the TL074 - why its so great and what to look for in an alternative. We asked 'guest' - the co-designer of the x0xb0x to drop some knowledge on us: the 074 is pretty much the toyota corolla of opamps. its not the best at anything in particular, but pretty good at everything. its the second cheapest opamp out there, comes in dip and soic, has relatively low current consumption, low distortion, and reasonable bandwidth and slew rate. the noise is ok-ish low, but the thing that really makes it an all around performer is the low bias current. its down in the pA range, which means you can use it for S/H or VCO,VCF, etc that require a range of currents down to the nAs. a lot of people used the LM358 because it is the cheapest opamp, but it has high bias current. the 074 can also handle high voltage rails which helps with SNR. it was designed for audio use, and was one of the first real mass market opamps back in the late 70s (if i recall correctly). the 741 was the first, and this was meant as an improvement over that. the 074 and 084 were made at the same time, and 074s were selected for lower noise, better distortion, and lower offset voltage, and then marketed at the audio market. the 084 was sold to everyone else. Who doesn't love the TL074? Apparently a lot of people - so let's look at a backup-option. It may not be as cheap/good but maybe it'll be in stock!
