• Please do follow the input and output connect as the picture above, the PCB Marked are wrong
• Please DO NOT connect input and output follow the PCB Marked, or would burn the module.
• This module has Constant current and Pressure limiting function. Can be used as adjustable boost power module, but also as a charging module.
• Simply limit the set output current (to replace the resistance of the R1R2 can change the output current)

• 1 x DC-DC Boost Converter ( Power Supply Module/Voltage Regulator/Adapter/Charging Module )
