Platima 8x8 WS2812B MCU/SoC Array - LEDs and Components, No Chip, V0.1

Overview

A GlowBit/NeoPixel style 8x8 panel designed to be used with a variety of MCU/SOCs, with tight packing and mounting holes for arrangement, as shown in video (insert video URL).

Specs

• Board Size: 80mm x 80mm
• Board Thickness: 1mm (FR4)
• Mount Positions: 8mm x 16mm
• Mount Hole: 2mm

There are two holes on each side of the board so that in a non-square pattern they can still hold rigid.

Functionality

Tested

• USB-C power input appears to work as it negotiates 5V on QC and PD lines
• Main 10A power pads appear to work fine
• Signal via DIN works fine as shown in video (note that isolation is only for USB-C lines)
• LEDs all work fine

Faulty in V0.1

• STM32F103 incorrectly wired to 5V, do not use it'll release the magic smoke
• USB-C ports not ideal location

Untested

• USB-C ports for DIN/DOUT operation
• RP2040 functionality
• ATmega328P functionality
• ESP32-WROOM-02 functionality

Once working and produced en-mass, these should be super cheap. Eg $12-16 ea I think! Currently charged at-cost whilst in development.
