Sorry if this has been posted. My google-fu is weak today.

What is the max power consumption of a Moteino with RFM69HW? (for spec'ing power supplies)

TIA,

Hmmm ... the MCU itself can take about 12-15mA. Then RFM69HW in transmit mode can take peaks of up to 130mA according to the SX1231H datasheet. If you RMS that it will be much much less. So I would ensure a power supply that can deliver at least 150mA for a safe margin. Batteries usually can do this without a problem.
