Overview
Rgbpmod is an open-source printed circuit board by pimdegroot, from the pimdegroot/rgbpmod repository on GitHub. It is a 2-layer board of 59.1 × 20.3 mm with 136 parts on 30 nets, routed with 761 tracks and 134 vias.
It is built around the GM1640S. Its parts include 40 diodes, 4 capacitors, 4 resistors, 2 switches and 1 IC. It belongs with the lEDs and displays boards of this library.

Introducion
In this repo you can find the design files and a code example for the rgb matrix pmod I designed. It is based on a 1x1mm RGB led and the GN1640 LED driver.
The leds used are: https://lcsc.com/product-detail/Light-Emitting-Diodes-LED_Foshan-NationStar-Optoelectronics-FC-B1010RGBT-HG_C158099.html
And the driver is: https://lcsc.com/product-detail/LED-Drivers_GN-GN1640_C265478.html
Note that the TM1640 is pin compatible and an english datasheet can be found for that chip.
When replicating this project it is highly recommended to order a stencil and use solder paste to solder the LEDs
Usage and Support
Feel free to use the design and code in this repo for your own project. Please credit this repo, or @mifune on twitter if you do.
This is a hobby project that I shared because there has been some interest in it. I will not offer it for sale (though I won't stop you from doing so). Please let me know if there is a file missing in the repo, other than that I won't offer support. I'm already working on the next project.

Questions
How big is the Rgbpmod PCB?
It measures 59.1 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rgbpmod use?
136 parts, built around the GM1640S. 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 Rgbpmod KiCad files?
From the pimdegroot/rgbpmod repository on GitHub, at the commit this page was made from: the board is rgbpmod.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rgbpmod design in my own project?
Its repository states no licence, so its author keeps all rights: ask pimdegroot before reusing the design.
