Yeah I didn't make a page for the 4.3 layout. I use the pinheader J2 for testing, the GND, 3V3, and P0 pins there. I power the board with 9V 10mA supply through 3V3/GND and power it up. Verify it is pulling less than 3mA (the power supply has a hard time reading this low and actual draw is <1mA). The output should be 8.95V or above on P0. Then I short the TC+ and TC- pins and the output voltage should drop to ~150mA or 5x whatever the room temperature is in Celsius. Power usage should not change.
