5A Constant Current/Voltage Step-Down Power Module
HEATSINK MIGHT NOT BE GLUED ON THE CHIP!!
  • Please connect right as the printed :"IN-,IN+,OUT-,OUT+",or the Module will be burned.
COMUNICATION PROTOCOL INSTRUCTION
  • This module can communicate with computer,so that the current and voltage reading can be displayed by the computer.
  • Because the output of this module is a TTL level,inorde to communicate with computer, thid=s level signal has to be transfered to a RS232 level which can recognize by the computer, this module(eBay item number:321254713986)is used to do this job.
BAUD RATE: 9600 Bps
