RAK13009 WisBlock QWIIC Module Datasheet

Overview​

Description​

The RAK13009 is a QWIIC module, which is part of the RAKWireless WisBlock Interface series. This module has two connectors: one for the WisBlock sensor and then for the standard QWIIC interface. By using this module you can plug any QWIIC interface module into the WisBlock sensor and use it just like any other WisBlock sensor.

Features​

  • WisBlock Sensor module
  • Standard QWIIC interface
  • Module Size: 10 mm x 10 mm

Specifications​

Overview​

Mounting​

The RAK13009 WisBlock QWIIC can be mounted to the IO slot of the WisBlock Base board. Figure 1 shows the mounting mechanism of the RAK13009 on a WisBlock Base board, such as the RAK5005-O.
