UVLO, Comparators with hysteresis (now with 20% more equations!)
The Mosquino board is intended to operate from very low-power sources, such as RF, vibration energy harvesting and small thermal gradients (e.g. body heat). Although the ATMega and the rest of the circuit can be put to sleep at < <1uA once they have reached legal operating voltage, many semiconductor circuits fail this test with…
