Figure 1: RAK19010 WisBlock Base Board with Power Slot block diagram
The WisBlock Power Slot module provides external interfaces to the whole board. RAK19010 will not work without
the Power Slot module attached to it.
The MCU in the WisBlock Core module offers the I2C, UART, and SPI data buses to the sensor modules. Through
these buses, the MCU can control and retrieve data from the sensors. Some types of MCU have fewer IO pins. In
such cases, not all pins of the data bus are connected. For example, only I2C and UART are connected.
Some MCU IO pins have an alternate function. In this case, you have the option to modify the IO via software or
rework the hardware to redefine the function of the IO. Refer to the datasheet of WisBlock Core to get all the
details.
Power Supply Diagram
Figure 2: RAK19010 power supply block diagram
The RAK19010 WisBlock Base board with Power Slot does not have a power regulator or other power-related
components. It gets a 3.3 V voltage supply and battery voltage supply lines from the Power Slot module attached
to it.
