Product Description

 

 

âThe module is adjustable buck module, you can adjust the module by adjusting the above blue sinking resistor to change the output voltage. Input and output voltage is 1V, the minimum output voltage of 0.8V.

âIN- (input negative), IN + (input positive), OUT- (output negative), OUT + (output positive) marked on the module must be connected correctly. Otherwise, the module may be damaged.

âBattery Charging Usage:
1. Determine the float voltage and charge current that you need to charge the battery, the input voltage of the module;
2. Adjust the constant voltage potentiometer, adjust the output voltage to 5V or so.
3. With the multimeter 10A current block output short-circuit current measurement, while adjusting the constant current potentiometer to output current to a predetermined charge current value;
4. Charging the turn-on lamp current is 0.1 times the default charge current (constant current value).
5. Adjust the constant voltage potentiometer to make the output voltage reach the float voltage;
6. Connect the battery and try charging.
(1,2,3,4,5 steps for the module input power, the output is not connected to the battery.)

âLED constant current drive to use:
1. Determine the operating current and maximum operating voltage that you need to drive the LED;
2. Adjust the constant voltage potentiometer, adjust the output voltage to 5V or so.
3. With the multimeter 10A current block output short-circuit current measurement, and adjust the constant current potentiometer to output current to reach the predetermined LED operating current;
4. Adjust the constant voltage potentiometer to make the output voltage reach the highest working voltage of LED;
5. Connect the LED, test machine.
(1,2,3,4 steps for the module input power, the output no load LED lights.)

âCommunication Protocol Description:
1. This module has the function of communication with the computer. Can facilitate the computer to read the module current and voltage data,

2. As the output of the module is TTL level, to achieve and computer communications, but also the level of conversion back to the computer can identify the RS232 level, need to use this cp2102 usb transfer TTL moduleTo achieve the 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)

among them

BB CC for the header (2 bytes)

ADDR is the module address (1 byte)

00 is a read current command (1 byte)

01 is the voltage read command (1 byte)

XX XX Any value (2 bytes)

CRC CRC check (1 byte)
