Has anyone done any testing to see what power the adafruit Radio Feathers / Breakout pull in sleep ?
Testing on the LowPowerLabs site says the RF modules should draw around 0.1micro amps in sleep.
In my testing I get the following which seems high (tested with Power Profiller Kit II)
RFM69HCW 433Mhz Radio Feather - sleep (LowPowerLabs rf69.sleep) - Approx 33 micro amp.
RRFM69HCW 433Mhz Radio Breakout - sleep (LowPowerLabs rf69.sleep) - Approc 90micro amps
RRFM69HCW 433Mhz Radio Breakout - EN pulled Low (3.3V regulator off) - Approx 33 micro amps
Does anyone have any thoughts on why so High ? All I can think of is both modules have 100K pull up resistors on CS and RST. If CS and RST had an input resistance each also of 100K then that would give a quiesant current of 3.3V / (100K) = 33mili amps.
