Mini Module
About the Mini Module
Mini Module is an open source PCB design by sullyjason, published on GitHub. It is a 4-layer board measuring 38 × 33.2 mm, with 25 components from 8 distinct parts.
By type, the board carries 4 resistors and 3 connectors.
It belongs with the displays & leds and iot & wireless designs in this gallery.
From the project
Interactive LED button grids that connect two locations over MQTT — press a button in one place, see it light up in the other. ESP32 + NeoPixel switch hardware, KiCad designs, and firmware.
3×5 grid of TL1 NeoPixel switches (7.5mm² each). 4-layer board with MCP23017 I/O expander mounted directly on the underside. Pinout is non-obvious due to space constraints — refer to schematic.
