From the project

A small PCB that allows you to create your own Minibadge displays!

This board provides everything your custom Minibadge display will need, including LiPo battery charging/use and USB-C power. It can be attached board-to-board with your own PCB designs, or it can be wired up using push-in WAGO wire terminals to your existing displays.

R2 Update list Better thermal management for voltage regulators under load. Updated PMIC ORing power path chip, replacing dual ORing diodes. Updated PFET for power on/off switching and system load capacity. Better thermal management for PFET under load. Improved current flow and reduced waste heat for CLK driver. Thicker power…
