Matrix click is a mikroBUS add-on board with two 5x7 matrices driven by two MAX7219 8-bit LED Display Drivers. The active area of each matrix is 7.62mm high and 5.08 mm wide. 7x5 is a standard resolution for displaying ASCII characters, so the click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The click communicates with the target MCU through the mikroBUS SPI interface with two separate Chip Select lines for each matrix (CSL for the left, CSR for the right). This board is designed to use a 5V power supply. |

8x8 R Click is an add-on board in the mikroBUS form factor. It's a compact and easy solution for adding an 8x8 LED matrix display to your design. It features the MAX7219 8-digit LED display driver module as well as 64 LED diodes. 8x8 Click communicates with the target microcontroller via four SPI lines (DIN, DOUT, CLK and CS). The board is designed to be powered by 5V, but can also communicate with 3.3V MCUs. |

4x4 RGB click carries a matrix of 16 WS2812 RGB LEDs and a MCP1826 low dropout regulator. These LEDs actually consist of three single colored LEDs (Red, Green and Blue), plus a control chip in a single package; various colors can be reproduced by mixing the intensity of each LED. However, don't drive the LEDs to maximum brightness because it will generate excessive heat and draw more current that advisable (up to 0.7A) which could potentially damage the mainboard. Also, don't touch the board when it's in use. The LED matrix is connected to the target board microcontroller through the mikroBUS RST pin. The board uses either a 3.3V or 5V power supply. |

7x10 R click carries a matrix of 70 red LEDs driven by a pairs of 8-bit serial-in, parallel-out shift registers, a Darlington Transistor array and a Johnson counter. 7x5 is a standard resolution for displaying ASCII characters, so 7x10 click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The click communicates with the target MCU through the mikroBUS SPI interface (SCK, SDO, SDI), with additional functionality provided by R CLK, MR#, LATCH and R RST pins. 7x10 R click is designed to use either a 3.3V or a 5V power supply. |

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. |

16x9 G click contains a green LED matrix and the IS31FL3731 audio modulated matrix LED driver. The dimension of the LED matrix is 16x9. Each LED can be controlled individually – both for on/off control and light intensity. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over I2C interface. |
