Fully assembled, tested and working battery power module and one CR2 3v lithium battery for the pico-mac-nano, 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.

This is a hand built, personal hobby project, not a commercial product. It has not been tested against any recognised safety standard and you use at your own risk.

See the user guide for more info and safety instruction. See our YouTube video on how to fit the battery module.
