Monday Kids 3.3-5.0V RGB LED Light Modulator Programmable PWM Controller for Arduino MOSFET Module 9600bps

1. Description:

1>. Onboard high performance microcontroller chip

2>. Onboard three-channel MOSFET tube, respectively control RGB LED lamps

3>. Onboard power LED indicator lamp and reset key

4>. Onboard input and output power connection socket

5>. Onboard serial port communication interface

6>. Control board power supply voltage: 3.3-5.0V

7>. PCB Size: 37.2*22.5mm

8>. LED controller board communication baud rate: 9600bps

2. LED Controller Board Communication Protocol:

1>. Data (1): start mark (defaults 0x1F)

2>. Data (2): channel number (1: red, 2: green, 3: blue)

3>. Data (3): brightness value (0-100%)

4>. Data (4): check code (the sum of above data)

3.>. For Example:

Set Auto Adjustment: 1F 00 00 1F

Set Red Lamp 1% Brightness: 1F 01 01 21

Set Red Lamp 50% Brightness: 1F 01 32 52

Set Red Lamp 99% Brightness: 1F 01 63 83

Set Green Lamp 1% Brightness: 1F 02 01 22

Set Green Lamp 50% Brightness: 1F 02 32 53

Set Green Lamp 99% Brightness: 1F 02 63 84

Set Blue Lamp 1% Brightness: 1F 03 01 23

Set Blue Lamp 50% Brightness: 1F 03 32 54

Set Blue Lamp 99% Brightness: 1F 03 63 85
