Viper plate v2 is an open-source printed circuit board by yulei, from the yulei/viper_plate repository on GitHub. It is a 2-layer board of 285.8 × 104.3 mm with 40 parts on 54 nets, routed with 534 tracks and 36 vias.
It is built around the TM1812. Its parts include 26 resistors, 2 capacitors and 2 connectors.
Main components

This plate uses 8 rgb leds to replace the indicator leds on the original viper/eagle pcb.
Two TM1812 were used to drive those leds. The protocol of TM1812 was almost the same as the WS2812 family, thus it's easy to integrate with commonly avaibly GH60 boards such as the DP60.
