BTnode Low-Power Modes
With both radios off, detailed analysis of the minimal power consumption of the Atmel AVR core was made. The results presented were measured with a 3.000 V input at the battery power supply and include the step-up regulator consumption to Vcc=3.3 V.
| mode | current [mA] | power [mW] |
|---|---|---|
| idle | 17.57 | 52.71 |
| ADC | 16.41 | 49.23 |
| ext-standby | 1.464 | 4.39 |
| power-save | 0.845 | 2.54 |
| power-down | 0.162 | 0.486 |
