This module is adjustable buck module, you can adjust the blue adjustable resistoron the module to change the output voltage. The input must be higher than the output about 1V. The minimum output voltage can be 0.8V. Battery charging method: 1 Make sure you need to charge the battery float voltage and charging current, the input voltage of the module; 2 Adjust constant potentiometer, the output voltage is regulated to about 5V. 3 Use a multimeter of 10A current to measure the output current of short-circuit current block, while adjusting the constant current potentiometer to make the output current reaches charging current value; 4 The charging turn lamp current's default is 0.1 times of the charging current (constant value) 5 Adjusting the constant voltage potentiometer to make the output voltage reaches the float voltage; 6 connected to the battery, try to charge. (1,2,3,4,5 step for powering the module input, the output load do not need to connected to the battery.) LED constant current drive methods: 1 Make sure the LED drive operating current and maximum operating voltage you need; 2 Adjust constant potentiometer, the output voltage is regulated to about 5V. 3 Use a multimeter of 10A current to measure the output current of short-circuit current block, while adjusting the constant current potentiometer to make the output current reaches LED operating current value; 4 Adjusting the constant voltage potentiometer to make the output voltage reaches the float voltage; 5 connected to the battery, try to operate. (1,2,3,4 step for powering the module input, the output load do not need to connected to the LED.) Communication protocol description: 1 This module has the computer communication function. Computer can be easily read data of the module's current and voltage, 2 As the module output is TTL level, if you want to achieve the communication withcomputer, you need to change the TTL level to the RS232 level which can be recognized by computer. 3 protocol as follows: Baud Rate: 9600 Bps BB CC ADDR 00 XX XX CRC (current return command) BB CC ADDR 01 XX XX CRC (voltage returns to the command) Among BB CC for the header (2 bytes) ADDR for the module address (1 byte) 00 to read the current command (1 byte) 01 is a read voltage command (1 byte) XX XX arbitrary value (2 bytes) CRC CRC checksum (1 byte) Package Include: 1 x DC Boost Power Module + 2in1 Volt Amp Panel Meter Packaging Details Unit Type:piecePackage Weight:0.131kg (0.29lb.)Package Size:15cm x 10cm x 8cm (5.91in x 3.94in x 3.15in)
