How to charge the battery:
1. Determine the float voltage and charging current of the rechargeable battery, the input voltage of the module;
2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;
4. The charge-to-light current is shipped by default at 0.1 times the charge current (constant current value).
5. Adjust the constant voltage position device to make the output voltage reach the float voltage; connect the battery and try to charge.
(1, 2, 3, 4, 5 steps are the module input power supply, the output is not connected to the battery.)
LED constant current drive How to use:
1. Determine the operating current and maximum operating voltage at which you need to drive the LEDs;
2. Adjust the constant voltage positioner and adjust the output voltage to about 5V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;
4. Adjust the constant voltage positioner to make the output voltage reach the maximum working voltage of the LED;
5. Connect the LED and test the machine. (1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the LED light.)
Description of the communication protocol:
1. This module has the function of communicating with the computer, which can facilitate the computer to read the module current and voltage data.
2. Since the output of this module is TTL level, it is necessary to realize communication with the computer, and also convert this level back to the RS232 which can be recognized by the computer. Level, you need to use this cp2102 usb to TTL module to achieve conversion.
3. The communication protocol is as follows: Baud rate: 9600 Bps
- BB CC ADDR 00 XX XX CRC (current return command)
- BB CC ADDR 01 XX XX CRC (voltage return command)
- Where BB CC is the frame header (2 bytes)
- ADDR is the module address (1 byte)
- 00 is the read current command (1 byte)
- 01 is the read voltage command (1 byte)
- XX XX any value (2 bytes)
- CRC CRC check (1 byte)
