I'm having trouble getting to the uA current levels that are touted with the Anarduino MiniWireless. I've tried to run a sketch which ONLY puts the avr to sleep. No serial or radio objects are ever instantiated, and I draw roughly 5mA on the Anarduino and 1.5mA on two different Moteinos (R4). I'm powering with 3.3V through the FTDI PWR pin. My multimeter is inline with the PWR signal, using a pair of jumpers. It's a cheapish $35 meter, but I've also used it to measure uA levels using the same voltage supply and a 10k resistor. I also ran the built in Blink sketch, and I draw roughly 11mA on the Anarduino and 8mA on the Moteino devices. Any idea what could be causing this high consumption?

Skim through this thread

TL;DR
1: Put everything to sleep. Including flash and radio module.
2: if you're using RFM69 desolder 10K D2 pullup resistor.
3: if your power source is stable, you could try bypassing voltage regulator
4: if you still need more savings, you could replace flash mem with more energy efficient (W25X40CL for example)
