STEMMA QT MCP23017 GPIO expander
from Adafruit Industries · host Adafruit Industries
We've gotten a lot of requests for a MCP23017 breakout and we've always sorta been like "ehh why not just use the DIP chip?" but with STEMMA QT we could see the use case for a plug and play version that comes with all the passives on board. so this breakout has 16 GPIO with matching ground pad. each gpio can have pullup, with 3 address pins, 2 irq pins, runs on 3 or 5V power and logic. we think this board is kind qt! #adafruit #stemma #MCP23017 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/ -----------------------------------------
