Debug history
23 August 2023
20 nano boards (Nano_1 to Nano_20) are setup for test. You can find the running code here.
During the setup, found some Nano boards(about 4 to 5) could not detected by computer. Some Nano boards(about 3) can work when connect to USB power, but did not work when only connect to battery, tested with multimeter and found their voltage was super low(bellow 0.5V).
24 August 2023
3 Nano stopped logging, and tested with multimeter and found their voltage was super low(bellow 0.5V). In total, 11 broken Nano boards were detected during the setup.

Jenny tested all the Nano boards we have (about 170), and found 12% are broken. Luke tested the faulty Nano boards and saw the same super low voltage issue. One Nano board got super hot immediately when connected to USB power.
14 September 2023
4 nano boards(Nano_5, Nano_6, Nano_8, Nano_12) stopped logging from 11 to 13 September. They have a same issue, all batteries run to 0V in 1 or 3 days after stop logging.
They all have radar sensor connected.
