Question/test request Could this work:

  1. Install your usb host samd library on a feather m0 bluetooth le
  2. Connect 3.7v lipo to feather
  3. Connect a keyboard by a 3.3v pro micro (with no leds/neopixels on the keeb) to the feather's micro usb via otg cable
  4. Have the feather power this not thirsty keeb running its firmware on a 3.3v mcu (and no leds in use), capture its keycode outputs over HID and forward them over ble hid to a laptop or ipad?
  5. Have the feather charge lipo as usual when connected to a usb port/charger instead of the keeb?
