Description
Module, using a 3-axis accelerometer and gyroscope, can measure the acceleration and angular velocity in three-dimensional space. For communication with the central unit, it uses the popular I2C (TWI) or SPU bus. The module has necessary for the correct operation of the system, passive elements.
Pins are holes for the popular goldpin connectors of 2.54 mm, for connecting the sensor viawiresor to directly attach to the breadboard. The strap must be purchased separately and self-soldered. The system also has a built-in temperature sensor operating in the range of -40 °C to 85 °C with a resolution of 12-bits.
Specification
- Supply voltage: 1.8 V - 3.6 V
- Current consumption: approx. 1 mA
- Three axes: X, Y, Z
- Communication interface: I2C (TWI) or SPI
- Resolution: 16-bits for each axis
- Measuring ranges (configurable):
- Accelerometer: ±2g, ±4g, ±8g, ±16g
- Gyroscope: ±125, ±245, ±500, ±1000, ±2000 °/s
- Built-in temperature sensor operating in the range of -40 °C to 85 °C with the resolution of 12-bit
- Built-in FIFO buffer of 8-KB
Since the maximum voltage, with which the system works, is 3.4 V, to work with Arduino necessary is a voltage converter. The exceptions are the modules operating with voltages of 3.3 V, for example, Arduino Pro Mini 328 - 3.3 V/8 MHz.

The product is compatible with Arduino To ease the operation with the module, the manufacturer has prepared auser's manual. |
Pins
The sensor has pins for mounting goldpin connectors - 2.54 mm pitch (not supplied, purchased separately and self-soldered).
| Pin | Description |
|---|---|
| VDD | Supply voltage from 1.8 V to 3.6 V. |
| GND | The ground of the system. |
|
SDA SDI |
The data line of the I2C bus (TWI). The data line of the SPI bus (MISO). |
| SCL |
Clock line of the I2C and (TWI) SPI bus. |
|
SDO/ SA0 |
Change of the I2C bus address - bit LSB. The data line of the SPI bus (MOSI). |
| CS |
Selection of the device of the SPI bus (chip select) - activated with the low status. When using I2C, the pin should be left unconnected. |
| INT1 | The output of the external interrupt (details in documentation). |
| INT2 | The output of the external interrupt (details in documentation). |
| OCS | Pins to use the FIFO buffer (details in documentation). |
| SCX | Pins to use the FIFO buffer (details in documentation). |
