Full color Rainbow Funduino Colorduino V2.0 Matrix RGB LED Driver Arduino projects robots NEW
The Colorduino is a RGB LED matrix driver platform basis on ATMega 328P. This design is to make user easily modify or write the firmware of Colorduino by Arduino IDE. Colorduino pairs the M54564 with a single DM163 constant current driver. By using the DM163, the Colors shield gains three 8+6-bit channels of hardware PWM control of the LED’s freeing up the MCU from having to implement it in software. This gives the ATmega more CPU bandwidth for performing other tasks. Colorduino is easy to cascade by IIC and Power interface.
8 bits colors support with 6 bits correction for each color in every dots
Hardware 16MHz PWM support
Without any external circuits, play and shine
Dedicated GPIO and ADC interface
Hardware UART and IIC communication with easy cascading
24 constant current channels of 100mA each
8 super source driver channels of 500mA each
The driver circuit based on 3 MBI5168 constant current sink drivers and a M54564 darlington source driver, the Colorduino pairs the M54564 with a single DM163 constant current driver. In order to better drive the RGB matrix and reach their best performance, we use the professional LED driver chip DM163 on board, by using the DM163, the Colorduino gains three 8+6-bit channels of hardware PWM control of the LED’s freeing up the ATMega328P from having to implement it in software. And the DM163 comprises shift registers, data latches, 8×3 channel constant current and 64 x 256 gray level PWM for per color! Each channel provide a maximum current of 60 mA.
So, each RGB dot has 256×256×256 = 16,777,216 colours (16 million) in theory, and it’s easy to use the 6bit correction register to calibrate the current error for each color LEDs
This shield can be programed via FT232 USB adapter
Power is supplied either by pin headers or via 2 sets of mini screw terminals, a slide switch selecting between the two. With the herder side, you just can use the 5V power supply, and in the terminal side, now support 6.2-7.5V power supply, more than 7V will cause the DM163 fever and more than 9V supply may burn your board. Pins brought out the edge of the board include RX, TX and DTS, which can be used to reprogram the onboard ATmega chip, and SCA and SCL for I2C communication. A green LED on the front of the board indicates power, although it is mostly obscured as soon as you plug the matrix panel in.
If you have an Arduino UNO, but just want to drive a RGB LED Matrix, you can consider this Colors shield, it’s compatible with Colorduino v2.0.
To make it work, you must need this RGB LED Matrix.
