Overview
Devboard is an open-source printed circuit board by meson800, from the meson800/modular-battlemap repository on GitHub, published under the MIT licence. It is a 2-layer board of 34.5 × 25 mm with 37 parts on 56 nets, routed with 263 tracks and 50 vias.
It is built around the CH340G, WS2812B-2020 and BSS138, with the EEU-FR1V330B among its other parts. Its parts include 12 resistors, 8 capacitors, 4 diodes, 3 ICs and 3 connectors. It belongs with the microcontroller boards boards and the STM32 boards of this library.

Goals
We want to make a modular battlemap system that:
- Consists of modular tiles, like 4x4 tiles at 25.4mm scale
- That tiles together with minimal whitespace
- That transmits power/data through the edges
- and is capable of arbitrarly lighting 4 RGB LEDs per square.
- can be powered / controlled from one "base map" tile, that has USB-C output.

Questions
How big is the Devboard PCB?
It measures 34.5 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
37 parts, built around the CH340G, WS2812B-2020, BSS138 and EEU-FR1V330B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Devboard KiCad files?
From the meson800/modular-battlemap repository on GitHub, at the commit this page was made from: the board is kicad/devboard/devboard.kicad_pcb and its schematic kicad/WS2812breakout/WS2812breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
