Programmable RGB LED Board System - Rectangular

is a system of programmable RGB LED boards which can connect together to make whatever 2D or 3D shape you want! All the boards are based on 1cm LED spacing and 10cm side. Through-holes enable use of standard 2.54mm headers, or you can wire directly to them if you prefer. Each shape has at least one set of inputs and outputs so they can be "aisy-chained"together. The straights have 3 sets of input/output holes so they can be connected at 180°, 90° or 45°.

This purchase is for the Straight-8 Matrix, which consists of a single 8 LED run on a 10cm straight strip. Please note, you'll need a driver board to drive it! (Sold Separately).

The Driver Board is a pHAT-sized driver board for with a buffer chip to handle the 5V logic levels and a space for external power if needed. Pi ports are broken out and there is space for an optional ADC, which enables control of your LEDs with potentiometers or sensors. uses SK9822 LEDs which are controlled using SPI.

With the system, you could make a

  • Light Pyramid
  • Mood light
  • Turn-signal/light system for your bicycle
  • Internet Clock (NTP)
  • TV simulator security device
  • Persistance of vision project
  • Natural light alarm clock
  • Controllable light source for macro photography/videography
  • Christmas or other holiday decorative lighting
  • Eye-catching wearable

Or embed them in any project that requires really fine control over colour and intensity of light! can be controlled by most popular electronics platforms, including

  • and Python (or any other language)
  • ESP8266 (e.g. Wemos D1 mini)
  • ATtiny (e.g. Digispark)

You could even control it from your phone, if connected to wifi-enabled device like the Pi Zero W. Open a port on your router and you could switch on your "V simulator"if you"e away from home (make it look like someone" home watching TV). But you can also hook up all sorts of other control mechanisms too, such as light, motion, sound or temperature sensors to trigger your LEDs.

Power Requirements

  • Each colour of each LED is rated at 20 mA, so a pyramid" 72 LEDs could draw as much as 4.3A at full tilt. In practice you never really use maximum brightness on all three colours at once.
  • For most applications you can take power from the Pi, if your PSU has enough juice. But, if you need to, you can connect an external 5V source and use the alternative connections on the driver board (or add supplementary wires directly to 5V/GND on the LED boards).
