Create custom LED art installations with the PIXEL Maker’s Kit. You’ll purchase your desired LED panels and corresponding power supply separately. Supported LED panels and power supply recommendations are listed below. Then simply upload your LED art design in animated GIF format using our Android app over Bluetooth (easiest option) or Raspberry Pi. The PIXEL board includes an onboard microSD card allowing you to download your LED art design which will loop indefinitely on the LEDs and then disconnect your device. Or leave your Android or Raspberry Pi connected and custom code an interaction application displaying art or scrolling messages using our open source example code including support for external sensors. Get the free apps from here which come included with over 180+ works of pixel art from leading pixel artists.
NOTE: The PIXEL Maker’s Kit is NOT compatible with iOS and only supports Android and Raspberry Pi.
The PIXEL Maker’s Kit includes:
- Pixel 2.5 Board
- LED Matrix Power Cable
- A to A USB 2.0 Cable
- MicroSD Card
- Bluetooth CSR4.0 USB Dongle
- External On/Off Switch
- LED Matrix IDC Ribbon Cable
The Maker’s kit does not include an LED matrix panel or power supply.
Choose from the following LED matrix panels of which most have been tested. Please do shoot us a note if you test one of the untested LED panels or find an additional panel and we’ll update this page for others. You can daisy chain multiple LED panels for a maximum resolution of 64×64 or 4096 LEDs. Instructables guide here for 64×64.
IMPORTANT DISCLAIMER: LED matrix suppliers do change standards for panels on their own and therefore you are at your own risk here especially with non-Adafruit panels. Adafruit will have better service and you will be able to return a defective or incompatible panel but at a higher price. Ordering from China (AliExpress) will be one and very difficult and expensive for returns.

The P number is the pitch or the distance from the center of one LED to the next. P6 is 6mm, P4 is 4mm, P3 is 3mm, etc. P3 would be the most dense / smallest display and P10 the least dense / largest display. All LED panels use the HUB75 standard. Note that while the connector looks the same, HUB08 panels will not work. WS28XX / neopixels LED strips are also not compatible.
Daisy Chaining Wiring Diagrams
IMPORTANT: The 4 pin LED matrix power connector on the PIXEL board can only be used to power one 32×32 panel as the DC jack connector on the PIXEL board cannot handle the current draw of multiple 32×32 panels. When powering more than 32×32, wire power to the LED matrices still from the same power supply but not through the PIXEL board.
|Two 64x32s = 64×64 (use this for the 64×64 panel too) In addition to the kit, you’ll need:2 IDC 16-pin ribbon cables (female connectors on both ends) at least 19″ long.5V, 20A Power Supply, you can use an old PC power supply too using the 5V output, just ensure it’s rated at 20A. You may also use an old PC power supply which will have a 5V output pin.The LED panels you purchase will come with the 4-pin LED power connectors. But you will need to splice the wires yourself per the diagram to the right.IMPORTANT: Follow the wiring diagram and ensure the LED panels are not getting power through the PIXEL board.|

Where to Buy
The PIXEL 2.5 Maker’s kit is currently available from Seeedstudio.
Theory of Operation
Unlike Arduino based methods, IOIO differs in that the firmware is taken care of for you. You have full control of the IOIO pins from within your application code using the supplied IOIO Java-based libraries; no additional Arduino sketches are required! This significantly simplifies the process, allowing you to focus solely on your application code and not having to worry about any board/firmware code. The firmware is upgradeable using the IOIODude application from your PC over USB.
IOIO has an active community of users who can be found on the IOIO users forum.
The PIXEL LED Matrix IOIO board is a customized IOIO board specially designed for controlling an LED matrix. The following IOIO pins are exposed on the PIXEL LED Matrix board via Grove ports. Grove is a 4-pin connector standard created by Seeedstudio allowing you to quickly plug in various Grove compatible sensors.
Open pins available for future expansion:
|Connector Type||IOIO Pins||Notes|
|Grove||6, 35, 5V, GND||GPIO, 5V (optional alcohol sensor)|
|Grove||4, 5, 5V, GND||GPIO, 5V|
|Grove||31, 32, 3V, GND||Analog or GPIO, 3V (optional proximity sensor)|
|Grove||33, 34, 3V, GND||Analog or GPIO, 3V|
|Grove||1, 2, 5V, GND||I2C, 5V|
|3-pin female||36, 3V3, GND||Analog or GPIO, 3V|
|6-pin male header||MCLR, 3V, GND, 38, 37. open||PICkit3 programmer interface|
The following IOIO pins are used for the LED matrix: 7, 10, 11, 19, 20, 21, 22, 23, 24, 25, 27, and 28
