Beam is a beginner-friendly PCB with 120 LEDs arranged in a 5x24 grid, a great size to display text or animations in your project. Plug in one to four to create a long blinky display that can be controlled by any 3-5V microcontroller or microcomputer (e.g. Arduino, Raspberry Pi, Particle, and more). The Beam boards communicate via I2C so you only need 2 pins! https://elecena.pl/product/17501863/beam-pluggable-led-boards-by-hover-labs 2021-04-07 https://elecena.pl/product/17501863/beam-pluggable-led-boards-by-hover-labs 2023-04-12
