DeepSleepr v0.1 connected to a Luckfox Core3566 (on a WaveShare base board) being tested. Then sleep mode current being measured standalone.

The meter software only has an accuracy of 100uA (0.1mA) and the meter itself only 10uA, but it didn't go over 30uA that I could see, and that is likely my inefficient use of the AMS1117-3.3 to resolve the I2C issues.

I had some minor design flaws in this version, such as missing I2C pull-ups, an unnecessary resistor on the UPDI line, and 5V traces being too thin, but v0.2 is about to go to production and has heaps of other improvements too!
