Fully assembled, tested and working battery power module and one CR2 3v lithium battery for the pico-mac-nano. This is the 1-bit rainbow implementation of the open source pico-mac project modified to run on a Pico Zero, and combined with a tiny 2" LCD screen and a custom designed PCB in a detailed, miniature, 62mm high replica Macintosh 128k case.

This optional module plugs into the pico-mac-nano PCB v3.2 or later and allows the unit to be powered from a single CR2 3v lithium battery rather than the USB-C port. It has a 3D printed frame and incorporates a voltage regulator, microswitch and switch rocker to allow pico-mac-nano to be turned on and off from a rear rocker switch. See our YouTube video on how to fit the battery module.
