Any thoughts/feedback on powering the nRF9160 Feather with two AA Alkaline cells?

    In parallel or series?

    Series should work but I haven’t tested this configuration. Parallel will likely not work and isn’t supported.

      Hi @jaredwolff , what about using a lithium ion (coin cell) as a ‘backup’ power source? Would this not work connected to the VBAT pin because they are not rechargeable?

      For context, I’m looking for a small form factor, always on power solution which would then switch to a different source when out of low power standby state.. Thanks

        aquafern if you’re using it to keep the RTC running that may be ok. (or even the nRF9160 in sleep) If you’re using the coin cell while LTE is active, that will not work. Transmission draws up to 500mA which is way too much for a tiny coin cell to handle.
