RAK12034 WisBlock 9-Axis Accelerometer Module Datasheet

Overview

Description

The RAK12034 is a 9-axis accelerometer module, part of the RAKwireless WisBlock Sensor series. It is based on BMX160 Bosch Sensor, which is a highly integrated low-power 9-axis sensor providing precise acceleration, angular rate, and geomagnetic measurement in each spatial direction.

Due to its small form factor and low-power consumption, it is ideal for smart wearables. Moreover, you can also use the BSX sensor data fusion software library of Bosch Sensortec to tweak the sensor's performance.

Possible Applications

Virtual and augmented reality
Indoor navigation
3D scanning/indoor mapping
Advanced gesture recognition
Immersive gaming
9-axis motion detection
Air mouse applications and pointers
Pedometer/step counting
Advanced system power management for mobile applications
Optical image stabilization of camera modules
Free-fall detection and warranty logging

Hardware

The hardware specification is categorized into five parts. It presents the coordinate system, pinouts and the corresponding functions and diagrams of the module. It also covers the electrical and mechanical characteristics that include the tabular data of the functionalities and standard values of the RAK12034 9-Axis Accelerometer Module.

Pin Definition

The RAK12034 comprises a standard WisBlock Sensor connector. The WisBlock Sensor connector allows the RAK12034 module to be mounted on WisBlock Base board, such as RAK5005-O.

The pin order of the connector and the pinout definition are shown in Figure 2.

Schematic Diagram

By default, the AP_AD0 pin is connected to VCC. And the default I2C address of the 9-Axis accelerometer is 1101001. R2 and R3 are not needed in RAK12034 due to pull-up resistors existing on the WisBlock Base board.
