The nRF24E1 microcontroller on Eco is capable of limited power management.

Power Modes of the MCU core:

1. -Full on (3mA)
   

2. -Idle / stop: the CPU is suspended but the clock is still running
   

3. -Power down: (2µA) the CPU is suspended; the clock is also stopped, although there is a 0.5--2.5ms shutdown display and a 1.0ms delay, assuming wake-up by RTC interrupt
   

Power Modes of the nRF2401 radio:

1. -Tx mode: 11.8mA@-20dBm, 12.4mA@-10dBm, 13.5mA@-5dBm, 1mA@0dBm
   

2. -Rx mode: 18mA@250Kbps, 19mA@1Mbps
   

3. -Standby: 32µA@16MHz
   

4. -Power-off: < 1µA
