NOTE
Detailed information about the RAK3372 LoRa PCB antenna can be found on the
Keep in mind that the PCB antenna is intended ideally only for prototyping and device evaluation. For
enterprise deployments, it is advisable to consider a better antenna for reliable performance.
⚠
WARNING
When using the LoRa transceiver, make sure that it is connected to an antenna. Using the transceiver
chip without an antenna can damage the system.
Make sure to fix the module with screws to ensure proper function.
Battery and Solar Connection
RAK3372 can be powered via the USB cable or Li-Ion/LiPo battery via the dedicated connectors, as shown in
Figure 9. The matching connector for the battery wires is a
This illustration uses RAK19007 as WisBlock Base. There are other
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 baseboard. Not all batteries have the same
wiring.
