Everyone loves the Aliexpress / Ebay clones of the Atmega328 based component tester from mikrocontroller.net. They're pretty useful, but mostly test at 5V maximum. This limitation prevents them from testing larger value zeners, higher voltage regulators, MOSFETs with large VGS, etc.
Is there a variant that handles these things correctly? I'd like it to cover all the regular stuff, too, like LCR, etc.
