Final power draw tests for QT Py ESP32 Pico

After all the functionality has been worked out with a new boards, its time to do last power draw checks to make sure that low power functionality is verified. historically, we haven’t cared too much about low power uses – stuff would be plugged into a 9V adapter anyways. but in the last couple of years we’ve tried to make whatever small changes we could to make our boards work well in deep sleep. this qt py esp32 pico can get down to 70uA which is pretty good! that means the cp2104 and neopixel are not drawing current. given we don’t have a 32khz crystal on board, we think this is as long as it gets! – video.
