A minimalistic 4x4 NeoPixel matrix controlled by an RP2040 Stamp. The board contains a three-way switch, a Qwiic connector, a LiPo connector, USB Type-C socket, and a power switch.
As the Photo Light is powered by the Stamp, you can run CircuitPython on it, as well as Arduino.
Make sure you use a 3.7V/4.2V LiPo with the Photo Light.
The board contains four M2.5 mounting holes, which could be used to attach a diffuser or a case to hold the battery.
