Hi. I want make a battery device and I need a board with low deep sleep power consumption and battery connector.

I check lolin32 lite and lolin c3 pico, and both have >400 uA .

I find that Firebeetle is a very good board (about 10uA), but… It is not cheap (17-18€) and I need a few devices.

Any recommendation?
