From the project

A RGB LED matrix pmod using the GN1640 driver chip

The leds used are: https://lcsc.com/product-detail/Light-Emitting-Diodes-LEDFoshan-NationStar-Optoelectronics-FC-B1010RGBT-HGC158099.html

And the driver is: https://lcsc.com/product-detail/LED-DriversGN-GN1640C265478.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
