New hack: KW203 modded with a STM8S003.

Sorry no PCB as this was a weekend project.  There are some additional component changes etc.

Why?  Most generic USB meters do not have sufficient resolution to see low current gadgets. My modded meter has a resolution of 1mA and can easily see the current drawn by the LCD meter (3mA) and my USB serial dongle (10mA).   It is a handy tool to have.
