BulbulHi! I know there's been a few people interested and i'm posting some progress I made today.
I've updated the connectors to 6 pin jst-ph for both the external battery and usb connections which means I'll need to redesign some daughter boards. Why the 6 pin for the battery? Main reason is I added another external connection for enabling the onboard voltage regulator. This will allow an external power switch to turn off/on the keyboard. Most Ble stuff is meant to be always on these days but there's just a comforting thought to know I can turn it on/off. Also by default I plan on using a single AA LiFePo4 so the battery charger is set up for that. You can use normal lion if you want but you'll have to change the resistor values if assembling your own. Other than the power path and breakouts the keyboard is largely the same. Same matrix and I haven't touched the switches. I don't have the money to test out the keyboard but I will probably be publishing files if anyone wants to give it a try before I get the chance. I may redesign it to have hybrid alps/mx for the solder on option footprint. cheers! I'll probably post an update once I clean up and upload the files.
