3.3.1 Battery switch P2
The Sense-D47 System can be powered with an optional LiPo battery, 2000mAh capacity. The battery switch P2 is used to disconnect the battery each time it is
necessary to preserve the battery charge capability, i.e. to avoid that it discharges completely (e.g. during system shipment). At first use, power the board using
connector P1 and slide the switch to the left position. In this position, the battery will be inserted and in charge.
