Description
Redesign of the initial PC-Integrated Laboratory Power Supply. Removed the fixed outputs and left the 2A adjustable output (1.2-20V) and connection points to link external boards with relay, current/voltage metering and etc. Removing the USB and isolation - these should be optional external boards and just took space on the board. This way the project is more versatile and the boards is much simpler. So this is what is left: - 1.2-20V 2A adjutable output with current/voltage measurements & current limiting - Full Automation via UART - Support for controlling 2 external boards for fixed power supplies (12V and 5V or whatever you want). Those can have current/voltage measurement and relay - Support for external SPI peripheral - whatever you want, could be GPIOs on the front panel or display?
