    You might want to see if the battery is just for the Real Time Clock. I don't remember if it could power the whole board.

    • Altimeter based elevation monitoring (MPL3115A2)
    • Air Pressure monitoring (MPL3115A2)
    • Temperature monitoring (MPL3115A2)
    • Ambient Light Level monitoring, buffered (TEMT6200)
    • 2 MBytes of low-power serial flash memory (S25FL216K)
    • Wi-Fi Communications module (LBWA1ZZVK7)
