Adafruit/Solderparty Keyboard Featherwing + Large JST battery case

thingiverse

I made this to fit my keyboard featherwing + esp32-s2 I got from pimoroni CHEAPER than I could have gotten it on Adafruit! I found this [this battery][] on Amazon which is the perfect size for this board. After my first test print, I found I couldn't get the battery in between the rails to hold the board up, so I made a way to slide it in from the bottom and let it drop down to stay in place. For my purposes, the hole at the bottom the battery goes to has a pinboard glued to it for now, with that pinboard wired up to my spare IO pins and power buses. This thing puts the m5stack + faces to shame! I wanted a rather sturdy feeling case, and this one is perfect with thick, hefty walls. I may design a faceplate and screw terminals next, but this suits my needs for now. Oh, and remember to SWITCH POLARITY on this battery if plugging it into the esp32-s2 feather! The negative/positive wires are opposite what the JST port on the esp32-s2 is expecting. While you switch those, you should also solder the MIC ENABLE jumper on the back, and a wire from the MIC pad to one of your analog inputs. Also not sure about keyboard interrupts yet, so I'm considering a wire from KBD TX to an IO line to act as interrupt just in case I can't figure out i2c interrupts.
