Product Configuration
Hardware Setup
The RAK13002 WisBlock IO Module is designed as an IO extension module that allows you to connect external
digital and analog modules to create a customized IoT solution. It supports two (2) I2C interfaces, two (2) UART
interfaces, one (1) SPI Interface, six (6) GPIOs, and two (2) ADC interfaces. For more information about
RAK13002, refer to the Datasheet.
The RAK13002 WisBlock IO Module can be mounted on the IO slot of the WisBlock Base board, as shown in
Figure 1. Also, always secure the connection of the WisBlock module by using compatible screws.
