# physically exposed on the XIAO -- only GPIO 0,1,2,16,17,18,19,20,21,
# 22,23 are broken out, and 18/19/20 are already the panel's SPI pins
# (CS/MOSI/CLK) while 0/1/2 are the buttons. Remapped to three of the
# remaining free pins; see docs/hardware.md for the full XIAO wiring

# Battery reporting: shares GPIO0/D0/A0 with the back button (a
# high-impedance divider coexists fine with the button's pull-up and
# deep-sleep wake -- the firmware time-shares the pin). Requires the
# 2x200k divider from BAT+ to GND, midpoint to this pin, described in
# docs/hardware.md. Off by default project-wide since most builds (the
# DevKitC-1 dev board) have no battery wired at all.
