A RP2040 based custom board with a matrix of WS2812 2020 LEDs. This little board is specially designed to play Tetris. From Arnov Sharma on Hackster.io:
This project began with the idea of using a WS2812B mini LED matrix as the display, paired with a microcontroller (Waveshare RP2040 Tiny) to control the matrix and handle all game logic.
To bring everything together, we designed a custom PCB that integrates a 14×20 LED matrix, input buttons, and a dedicated power management circuit. The entire system is powered by a LiPo cell, with an onboard power management IC responsible for charging and discharging the cell.
