5. Wide range of applications
Supply voltage: DC 3.3V-5V
Board indicator: power indicator
TTL baud rate: 9600
R, G, B: R for red, G for green, B for blue
Driving RGB: suitable for driving a single RGB lamp bead of common cathode type or a light bar with multiple lamp beads connected in parallel
GND: Connect to the common cathode of RGB
+- : input power
VCC: connect to TTL 5V (connect one to the power supply port of the board)
RX: connect to the TX end of TTL
TX: connect to the RX end of TTL
GND: Connect to the GND terminal of TTL
(1) Each instruction consists of 4 bytes of hexadecimal (hex) data, and each
The meaning of the table is as follows:
data (1) --- Revelation ID (default is 0x1F)
data(2) --- channel number (0x01: red, 0x02: green, 0x03: blue)
Data (3) -- brightness value (range: 0x00--0x64, equivalent to 0-100 in decimal)
Data (4) -- check code (the sum of the first three data)
(2) This module includes manual dimming and automatic flashing function of the system, sending 1F
00001F to turn on the automatic flash function
(3) Some manual dimming instructions are as follows:
Set red light 1% brightness: 1F01 0121
Set red light to 50% brightness: 1F 0132 52
Set red light 99% brightness: 1F 0163 83
Set green light 1% brightness: 1F 020122
Set green light to 50% brightness: 1F 02 3253
Set green light to 99% brightness: 1F 0263 84
Set blue light 1% brightness: 1F 0301 23
Set blue light to 50% brightness: 1F 033254
Set blue light to 99% brightness: 1F 03 63 85
The setting rules of other colors and brightness are the same as above, the basic steps: start bit ->
Channel number -> luminance value converted to hexadecimal -> add up the first three digits:
For example: red light 0% brightness: 1F01 0020
Green light 75% brightness: 1F 024B 6C
Blue light 100% brightness: 1F 03 64 86
This controller is suitable for controlling a single RGB lamp bead or multiple lamp beads of common cathode type and
The RGB light strips connected together, the current limiting resistance of the LED lights can be customized according to your needs.
You can choose the appropriate resistance value according to your actual needs. The controller accepts serial commands by
order to control the color and brightness of the LED, the VCC of the USB to TTL serial port module,
TX, RX, GND are respectively connected to VCC, TX, RX, GND of RG controller (such as
No response to the command, try to exchange TX and RX), R, G, B, GND at the output
Connect to R, G, B, GND of LED respectively, - the default is automatic flashing mode when power on,
Open the serial port debugging software (such as SCOM32) on the computer and send the dimming command to enter the
Manually adjust the lights.
