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...
Found application note of a previous model module.
