Datasheet

There are two large A and B buttons, connected to

digital #4 (Left) and #5 (Right) each. These are

unconnected when not pressed, and connected to 3.3V

when pressed, so they read HIGH. Set the pins #4 and

#5 to use an internal pull-down resistor when reading

these pins so they will read LOW when not pressed.

This small button in the center of the board is for

Resetting the board. You can use this button to restart

or reset the CPX.

If using Arduino or CircuitPython, press this button once

to reset, double-click to enter the bootloader manually.

If using MakeCode, press this button

twice

to reset,

once to enter the bootloader manually.
