The LED SHIM is a slim bar of 28 RGB LED pixels that slips directly onto your Raspberry Pi's GPIO pins — no soldering required. Its friction-fit header provides a secure connection, and at just 0.8 mm thick, it can be used alongside HATs and pHATs without interference, peeking out visibly at the top of the board.
Driven by the IS31FL3731 LED matrix driver chip, LED SHIM provides individual control of all 28 pixels with full RGB colour mixing. A Python library with one-line installer and example scripts makes it easy to get started.
Key Features
- 28 RGB LED Pixels – Single-row bar with individually addressable LEDs

- Ultra-Slim – 0.8 mm thick PCB, compatible with stacked HATs and pHATs
- IS31FL3731 Driver – Hardware LED matrix driver for smooth, flicker-free control
- Python Library – One-line installer with example scripts included

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
