Colorduino - 8x8 RGB LED Matrix Driver Board
40,00 USD
Arduino does not have enough PWM pins to pilot a 8x8 RGB LED matrix. So, it needs external driver circuits. Colorduino is an Arduino Uno compatible 8x8 RGB LED driver board.
The DM163 constant current LED driver provides peripheral PWM. This feature allows to apply 8 - bit PWM signal to each red, green and blue channel. Consequently, it is possible to generate 16 million diffrent color signal for each pixel.
There is an Atmega328 microcontroller on the board. So it is possible to program Colorduino using Arduino IDE. There is not any programmer chip on this board. To program the board, you may choose an external Usb to serial Convertor .Colorduino boards are able to connect themselves to build a bigger matrix. It is possible to connect these boards via 8-pin interafaces. The boards use I2C protocol to communicate.
Ther are two options to supply Colorduino. First, it is possible to supply the board via 8-pin interface using VDD and GND pins or the other option is to apply 6.5 - 7.5 V via VIN and GND connectors.
