Matrix RGB click

MIKROE-2239

25 g

Matrix RGB click is a mikroBUS™ add-on board powered by a 32-bit FT900 MCU designed specifically for powering 16x32 RGB LED matrices. The board has a 16 wire IDC connector for connecting to a single 16x32 LED panel; however, the firmware inside the FT900x chip can drive more than one panel. Multiple panels can be connected to each other into a daisy-chain configuration (see the video).

Matrix RGB click communicates with the target MCU through the SPI interface. It uses a 3.3V power supply only. Complete ​kits with Matrix RGB click, a single 32x32 RGB LED matrix panel (consisting of two 16x32 matrices joined together), and a power supply unit are available to order.
Alternatively, panels and power supplies can be purchased separately.

Features and usage notes

RGB Panels are driven by shift registers. There are 9 shift registers for driving LED colors and row selections effectively, along with 3 pins to latch, clock and enable leds. There are 2 for each color, 3 for row selection( A, B, C ), clock pin ( CLK ), latch pin ( STB ), and a OE / enable pin. Top row color shift registers are labeled R1, G1 and B1, while bottom row color registers are labeled R2, G2 and B2. Row selection registers are used to make re-writes appear more fluent. While your row selection is set to row 0, row 8 will also be updated. Shifting data onto R1, B1 and G1, will update row 0 data, and R2, B2, and G2 will update row 8.

Multiple panels can be connected to each other into a daisy-chain configuration (see the video). Matrix RGB click communicates with the target MCU through the SPI interface. It uses a 3.3V power supply only.

A detailed development guide is available on the learn page.

However powerful, Matrix RGB click is only a driver board, and you need to have one or more RGB panels and a power adapter to see the output. Make sure to buy them along with the click.

A full Matrix RGB development kit is also available. It includes matrix RGB click, 32x32 RGB LED Matrix Panel - 6mm pitch, 12V-3A power supply with EU plug (can power up up to two panels)

Programming

This snippet shows how to initialize the matrix, add scrolling text, scroll bitmap images, all with different colors and speeds very easily.
