README
README.mdColour Maximite 2 - JLC-ready design
Overview
This is a open-source hardware clone PCB of the Colour Maximite 2 computer.
It's fully compatible to the original firmware and software.
- Designed for automated assembly at JLCPCB, everything except the connectors can be machine assembled.
- USB-C port (instead of USB-B) for serial and power
- microSD socket instead of full-size SD socket
- STM32 and SDRAM directly onboard, no expensive evaluation board needed

Rev.A Errata
- Missing mounting holes
- SDRAM pinout is missing A12 line (causes instability, fixed in Rev.B, workaround with enamelled copper wire of the same length as the other traces)
- SRV05 diode package had the Pin 1 indicator at Pin 6.
- Nunchuck footprint is reversed
Rev. B Errata
- KiCad Bug caused data corruption in PCB files, board files were reset back to pre-RevA state (missing via stitching). Will still work.
- SRV05 diode package had the Pin 1 indicator at Pin 6.
- Nunchuck footprint is reversed
Rev. C Errata
- SRV05 diode package had the Pin 1 indicator at Pin 6.
- Nunchuck footprint is reversed
Rev. D Errata
- SRV05 diode package had the Pin 1 indicator at Pin 6.

Questions
How big is the CMM2-JLC PCB?
It measures 130 × 102 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CMM2-JLC use?
111 parts, built around the CP2102N-A01-GQFN28R, DS18B20, AMS1117-3.3 and MT48LC16M16A2P-6A:G. 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 CMM2-JLC KiCad files?
From the Manawyrm/CMM2-JLC repository on GitHub, at the commit this page was made from: the board is CMM2-JLC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CMM2-JLC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
