Haven't updated in a while, but still working hard on this. Decided to add the debugger to the board for cmsis-dap debugging, a com port and drag and drop programming. Also added a USB hub so it will still be usable as a USB or Bluetooth keyboard. Software is doing good too I've got my power usage alnost dialed in, the apa102 draw around 80ma when off so they and the signal lines to them are now switched so you can turn them completely off when not being used . All the LEDs for the nrf, battery charger, and debugger have a common solder bridge for each chip so they can be disabled or enabled. There's more but should be getting another round of pcbs made up soon that should be the final one... Hopefully.
