About the Bc250 carrier PCB

Bc250 carrier is an open source PCB design by peterdk31, published on GitHub. It is a 2-layer board measuring 80 × 34.5 mm, with 13 components from 13 distinct parts.

By type, the board carries 11 connectors, 1 transistor and 1 resistor.

It belongs with the displays & leds designs in this gallery.

From the project

A small controller + receiver (esp32) for controlling a string of ws2812b leds. It installs a daemon that can switch between different effects based on some defined rules.

An 80 × 34.5 mm two-layer carrier for the ESP32-C3 Super Mini that runs the receiver firmware in the BC-250. It replaces the loose wiring for the power switch, the WS2812B strip and the fans with one board: the Super Mini plugs into two sockets on it, the PSU's own 10-pin Mini-Fit Jr plug goes straight onto a right-angle header and lies flat over the board, the strip leaves through a 10 A JST-VH, and the illuminated power button plugs into a 4-pin JST-XH. A 2 × 6 pin header along the left edge (J11) takes the sense wire and breaks out the module's five spare GPIOs, each beside a ground pin…
