BMA220 3-axis I2C digital accelerator - DFRobot module
Sensor for measuring acceleration in three axes. It is characterized by small size, low energy consumption and simple use. It communicates via the I2C bus.
For communication with the central unit, the popular I2C bus (TWI) is used. The module has, necessary for the correct operation of the system, passive elements. Leads are popular goldpin connectors (in the set for self-soldering), for connecting the sensor via wires or for connecting directly to breadboard.
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
The product is compatible with Arduino Manufacturer prepared a libraryanduser's guidefor users ofArduino. |
Pins
The sensor has five pins for mounting the goldpin connectors - 2.54 mm pitch (not included).
| Name | Description |
|---|---|
| VCC | The module's supply voltage ranges from 2.0 V to 3.6 V. |
| GND | The ground of the system. |
| SCL | Clock line of the I2C bus (TWI). |
| SDA | The data line of the I2C bus (TWI). |
| INT | External interrupt output (details indocumentation). |
Resolution
Data about the resolution and sensitivity of the sensor are presented in the table below.
The registry range | Range | Sensitivity | Resolution | Example of usage |
|---|---|---|---|---|
| 00 | ± 2 g | 16 LSB/g | 62.5 mg / LSB | Orientation recognition |
01 | ± 4 g | 8 LSB/g | 125 mg / LSB | Games |
10 | ± 8 g | 4 LSB/g | 250 mg / LSB | Games |
| 11 | ± 16 g | 2 LSB/g | 500 mg / LSB | Detection of vibration |
