RAK4631 can be powered via the USB cable or Li-Ion/LiPo battery via the dedicated connectors, as shown in
Figure 11. The matching connector for the battery wires is an
JST PHR-2 2 mm pitch female .
This illustration uses RAK5005-O as WisBlock Base. There are other WisBlock Base boards available and you
need to check the datasheet of the specific WisBlock Base board for the right polarity and other parameters.
⚠ WARNING
Batteries can cause harm if not handled properly.
Only 3.7-4.2 V Rechargeable LiPo batteries are supported. It is highly recommended not to use other
types of batteries with the system unless you know what you are doing.
If a non-rechargeable battery is used, it has to be unplugged first before connecting the USB cable to
the USB port of the board to configure the device. Not doing so might damage the battery or cause a
fire.
Only 5 V solar panels are supported. Do not use 12 V solar panels. It will destroy the charging unit and
eventually other electronic parts.
Make sure the battery wires match the polarity on the WisBlock Base board. Not all batteries have the
same wiring.
