A chainable 8x8 LEDs RGB matrix easy to assemble and to drive
This 6cm square matrix is made of RGB LED that can be driven with SPI interface and a quite simple open-source protocole (made public by Olimex).
The matrix can be daisy chained together to creates a bigger display. As the RGB LEDs can be driven individually, each pixel can displays 7 colors (red, green, blue and combinations). The LEDs are not driven with PWM controler, so the number of colors availables on the matrix is limited to 7 colors.
Olimex did create the Arduino code to support this matrix and MC Hobby did make a MicroPython portage of it. As the protocol to transfert the data is simple, it can be adapted to other MicroControler and programming langage.
- 36x RGB LEDs on a 8x8 matrix
- LEDs controled via SPI through a pre-programmed PIC16F1503
- Separate power supplied of 5V DC (either from host board or externally).
- Works with data signal at 3.3V
- Easy to stack/chain multiple ones to build any LED matrix
- Library & demo for Arduino made by Olimex
- Library & demo for MicroPython made by MC Hobby
- ICSP pads available for uploading custom firmware in PIC16F1503 (as needed)
- UEXT capable to connect to device or host microcontroller (organised in a row)
- Dimensions: 60.0 x 60.0 mm
- 4 mounting cuts for firm positioning
