Desk of Ladyada - Macropad Bringup & Calculator Py
from Adafruit Industries · host Adafruit Industries
This week on the Desk of Ladyada we're doing the bringup of our hopefully-final revision of the RP2040 macropad we're working on. Arduino is working solidly, and CircuitPython is getting there. We have to get the OLED driver bugs ironed out but the hardware seems solid! Next up, we've acquired a TI calculator running a fork of CircuitPython. Let's check it out and see what has been added. The Great Search - SMT PTC Fuses https://www.digikey.com/short/24zcmdwc For the KB2040 board we're working on, we want to add a PTC fuse. These fuses auto-'heal' after they cool down and they're pick and place friendly, so they're easy to use. We're going to add one to this board so it has similar behavior as the Pro Micro it is pin-compatible with. PTC fuses are available in a few different voltages, current ratings and sizes - lets find the one we need for this tight-fit PCB! #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/ -----------------------------------------
