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 are matching the polarity on the WisBlock Base board. Not all batteries
have the same wiring.
Software Configuration and Example
The RAK1920 module is a sensor extension module, it supports several defacto-standard interfaces in the IoT
market and allows customers to integrate sensors manufactured by Mikroe, SparkFun, SeeedStudio, and others.
For example, the RAK1920 supports the Click Boards™ series of modules provided by Mikroe, Qwiic Connect™
sensor interface designed by SparkFun, and it supports all kinds of I2C module digital I/O, UART and ADC
sensors with a Grove™ interface.
Initial Test of the RAK1920 WisBlock Module
If you already installed the
, the WisBlock Core and example code should now be
available on the Arduino IDE.
1. You need to select first the WisBlock Core you have, as shown in Figure 6, Figure 7 and Figure 8.
