Power Supply
From external power supply
Power supply
Supply voltage is 4.7-15V. The average consumption of the board is 1.5-2 watts. But since the GPRS module consumes up to 8W impulsively, it is recommended to use power supplies with a power of at least 10W.
5.5x2.1mm power connector, also input voltage can be connected to terminals 1 and 26.
Power over Ethernet
Power over Ethernet cable is supported, Passive PoE voltage from 7 to 16 Volts. Power is transmitted in unused pairs: "+" ("-") pair 4-5 (blue, white and blue), "-" ("+") on paired 7-8 (brown, white-brown). Polarity doesn't matter. Connecting PoE with the power supply causes damage to the power supply.
Battery
Battery
The Wiren Board allows you to connect a Li-Ion (Li-Pol) battery with a maximum voltage of 4.2 V. When you connect the power, the battery is charged with a current of up to 0.5 A (depending on the load). There is protection against over-discharge of the battery, at a voltage below 2.9 V the battery is disconnected. However, it is recommended to use protected batteries.
Also, there is no protection from charging at low temperatures. Be careful, the batteries deteriorate from this.

Debug UART
Debug UART выведен на разъём UEXT1, а также отдельно на гребёнку (рядом с аудиовыходом, см. схему)
Для Debug UART используются ножки 2,3,4 (см. рисунок).
