Reply To: Power usage of Mayfly1.1 with Hydros 21 cTD and LTE BEE cell modem

We’ve published some sample power usage readings over the years, but it varies by station configuration and board version and a few other settings.  But in general, a Mayfly v1.1 revB board with an EnviroDIY sim7080 LTEbee will use about 8 mA at idle, 0.650 mA in sleep mode, and a max of 110 mA for a few seconds when actively transmitting.  But your most accurate numbers are going to come from doing your own power measurements after you’ve programmed a board to work with whatever hardware you’ve selected.
