Arduino Hot Plate (3) - cooking with AC

wolfgangfriedrich

Edit: Added initial test results. After some tests with larger plates and Arduino sized PCBs it turned out that 100W USB-C power was not enough for my Hot Plate to get enough heat into the PCB to melt the solder reliably. It was more like a warm...
