<p>A good and stabilized power supply is essential to have error free operation. The device is quite picky in terms of proper power supply. Especially the wifi module have some load spikes which the power supply needs to cover. If the power is not stable enough, the brwonout mechanism is protecting against strange behaviour and force a reboot whenever the voltage drops below a specific level.
