Desk of Ladyada - STEMMA QT & Microphone Breakouts
from Adafruit Industries · host Adafruit Industries
On yet another stemma sunday, we're revising our ancient HT16K33 LED backpacks to include QT connectors - we're also going to try to 'unify' two or three of the layouts so they can share the same PCBs. We're also interested in redoing some of our microphone breakouts so they're easier to use in a classic stemma breakout shape. We put together both electret and MEMS versions The Great Search - MEMS analog microphone https://www.digikey.com/short/d2w32b4d We're now used to parts being unavailable, and when designing a new board we noticed the MEMS microphone we've used before, SPW2430, is NRND. Let's look at some alternatives for analog MEMS mics! #deskofladyada #thegreatsearch #adafruit 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/ -----------------------------------------
