Description
Stop scrolling! And take a moment to appreciate the simplicity and elegance of a bright white LED, so often overlooked next to its flashy RGB cousins. Pico Scroll Pack incorporates 119 white LEDs in a tidy 17×7 matrix, along with four tactile buttons for interacting with your Pico-based contraption. OK, you can start scrolling again.
The brightness of each LED is individually controllable, and it’s very nice for displaying graphs, scrolling messages, soothing snowfall animations or for visualising cellular automata. Shiny.

Pinout
Pico Scroll Pack talks to the IS31FL3731 LED driver chip over I2C requiring only SDA and SCL pins.
The four switches are wired up as SW_A, SW_B, SW_X, and SW_Y.
Power is supplied through VSYS meaning that you can use Pico Scroll Pack both on USB power and from external supplies (so long as they can supply 3V+) making it ideal for battery powered projects.
This leaves the majority of pins on your Pico free for other uses!
