Al Programmable Full-Color RGB LED Dimming device Modulator PWM Control Panel
Description:
1. On-board high-performance microcontroller chips
2. On-board three way MOSFET tube, respectively control the RGB tricolor LED lights
3. On-board power LED lights and reset buttons
4. On-board the input and output power socket
5. On-board serial port communication interface
6. Panel power supply voltage: 3.3-5.0 V
7. PCB size: 37.2 (mm) x22.5 (mm)
8. LED panel default communication baud rate: 9600 BPS
The LED panel communication protocol
- Data (1) - startup logo (the default is 0 x1f)
- Data (2) - channel number (1: red, 2: green, 3: blue)
- Data (3) - brightness value (0-100%)
- Data (4) - check code (the sum of the top three data)
Ex. :
- Set to auto lamp: 1 00 00 f 1 f
- The red lamp 1% brightness: 1 f 01 01 21
- The red lamp 50% brightness: 1 f 01 32 52
- The red lamp 99% brightness: 1 f 01, 63, 83
- Set the green light 1% brightness: 1 f 02 01 22
- Set the green light 50% brightness: 1 f 02 32 53
- Set the green light 99% brightness: 1 f 02 63 84
- Set the blue light 1% brightness: 1 f 03 01 23
- Set the blue light 50% brightness: 1 f 03 32, 54
- Set the blue light 99% brightness: 1 f 03, 63, 85
