README

Cheap Crappy Constant Current Portable Programmable Power Supply

CCCCPPPS is a DIY Programmable Buck/Boost Power Supply, designed with the goal of being cheap, crappy, but very useful!



Usage

Web UI

https://bogdanthegeek.github.io/CCCCPPPS/software/webui/index.html

Debug Interface:

This interface is enabled by default when building the firmware. Use minichlink to issue commands listed below

Commands

[!NOTE] Need to improve the command list and handler

  • 0 to turn the supply off
  • 1-9 to set the target Voltage/Current in multiples of 1000mV/100mA
  • c to switch to Constant Current Mode
  • v to switch to Constant Voltage Mode
  • + to increase the target Voltage/Current depending on mode, in 50mV/25mA increments
  • - to decrease the target Voltage/Current depending on mode, in 50mV/25mA increments
  • Konami code makes the unit self distruct. Removed due to misuse.
