Hi.
This newer module step-sets the output voltage by +, - touch buttons on the bottom right; is is not the same as similar ones that use a potentiometer :


Uses a XL4015E1 chip, and a MCP6002i. Probably made by 'WHDTS' Do you know its schematic ?

There is a chip under the numerical display to drive it, and unless it has additional features; the method to step voltage has me scratching my head...
That chip will be a microcontroller, doing all the work.

The datasheet for the regulator chip doesn't really help, that's easily available and obviously doesn't mention any extra control circuitry.
