Time Lapse Prototype Build! Adafruit PCF8575 I2C 16 GPIO Expander Breakout - STEMMA QT / Qwiic 🔧🔌⚙️

Expand your project possibilities, with the Adafruit PCF8575 GPIO Expander Breakout - an affordable 16 channel I2C expander. GPIO expanders work like this: you have a board with some number of GPIO but not enough for your project - maybe you need more buttons or LEDs. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them. It's going to be slower than direct GPIO access, but maybe that doesn't matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I/O control! https://www.adafruit.com/product/5611 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #adafruit #opensource #opensourcehardware #PCF8575 #timelapse electronicsengineering #prototypebuild #gpioexpander #i2c #stemmaqt #diyprojects #makersgonnamake #hardwarehacks #affordabletech #expandableio
