Pico Scroll Pack - addon for Raspberry Pi Pico

Pico Scroll Pack - addon for Raspberry Pi Pico

A sparkly 17x7 grid of snugly packed, individually controllable white LEDs to bling up your Raspberry Pi Pico, accompanied by a quartet of useful buttons.
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 17x7 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 visualising cellular automata. Shiny.

Pico Scroll Pack Features:

• 17x7 matrix of white LEDs (119 total)
• Individual PWM brightness control of each LED
• IS31FL3731 LED matrix driver chip, I2C address: 0x74
• 4x tactile buttons
• Pre-soldered female headers for attaching to Pico
• Compatible with Raspberry Pi Pico.
• Fully assembled
• No soldering required (as long as your Pico has header pins attached).
• Dimensions: approx 65mm x 25mm x 10mm (L x W x H, including headers and buttons)
• C/C++ and MicroPython libraries

Pico Scroll Pack Notes:

• A Raspberry Pi Pico is not included - click here if you'd like to buy one!
• Your Pico will need to have male headers soldered to it (with the pins pointing downwards) to attach to our add-on boards.

Pico Scroll Pack Getting started:

The labels on the underside of Pico Scroll Pack will show you which way round to plug it into your Pico - just match up the USB port with the markings on the board.
The easiest way to get started with our Pico add-ons is by downloading and copying our custom MicroPython firmware to your Pico, it includes all the libraries you'll need.
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!
