Figure 1: RAK19001 WisBlock Base block diagram
The MCU in the WisBlock Core module offers the I2C, UART, and SPI data buses to the sensor and IO modules.
Through these buses, the MCU can control and retrieve data from the sensors. The RAK19001 WisBlock Base
board connects all these modules.
The RAK19001 is designed to be powered by either rechargeable or non-rechargeable battery. The rechargeable
battery it supports is Li-Ion and provides the necessary charger IC on-board. The charger circuitry can be
connected to a wall outlet charger through the Type-C USB connector or via the solar panel connector.
A high-efficiency step-down converter with a low quiescent current is used for generating 3.3 V. This 3.3 V power
supply drives the consumption of the WisBlock Core module and the sensor modules.
3V3_S is another 3.3 V power supply, it can be controlled by the MCU to disconnect the power to the sensor and
interface modules during idle periods. 3V3_S is controlled by an IO2 pin on the WisBlock Core board.
Set IO2=1, 3V3_S is on.
Set IO2=0, 3V3_S is off.
Hardware Setup
RAK19001 WisBlock Base Board Installation Guide
RAK19001 WisBlock Base Board is the main board that allows you to attach MCU, sensors, and IO modules
through the standardized expansion connectors. These connectors provide a data bus interconnection between
the modules attached to the RAK19001 Base Board.
This guide shows the details related to the installation of modules into the RAK19001 Base board.
Attaching a WisConnector
The WisConnector is the interface between the RAK19001 module and the WisBlock Core, Sensor, and IO
modules. Before connecting these modules, read the following instructions:
