13DOF Click Board

The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement based on proven sensing principles, housed in an extremely compact metal-lid LGA package. Its small dimensions and its low power consumption enable the integration in battery-powered or frequency-coupled devices, such as handsets or wearables. The BMM150 geomagnetic sensor, a three-axis geomagnetic sensor and the BMI088 sensor module are both featured prominently and are key parts of the 13DOF Click Board™.

How Does The 13DOF Click Board™ Work?

The 13DOF Click Board™ is based on the BME680 and the BMM150 sensor ICs. Also, the click contains BMI088 - a small, versatile 6DoF sensor module from Bosch. Altogether, this Click board™ integrates a triaxial accelerometer, triaxial gyroscope, triaxial geomagnetic, gas, humidity, pressure and temperature sensors on the single board. This allows very high integration and very small dimensions, at an affordable cost. The output of each MEMS is processed, digitized and available through the I2C communication interface. The data can be oversampled by the sensor ICs by themselves, in order to achieve as reliable data readings as possible. As already mentioned, the features of this click are numerous.

The BMM150 geomagnetic sensor from Bosch is a standalone sensor for consumer market applications. It allows measurements of the magnetic field in three perpendicular axes. The sensor is carefully tuned and a perfect match for the demanding requirements of all 3-axis mobile apps such as electronic compass, navigation or augmented reality. An application-specific circuit (ASIC) converts the output of the geomagnetic sensor to digital results which can be read out over the industry-standard digital I2C interface. The package and interfaces of the BMM150 have been designed to match a multitude of hardware requirements. As the sensor features an ultra-small footprint and a flat package, it is ingeniously suited for mobile applications, such as cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features, game controllers, and others.

The BMI088 is an inertial measurement unit (IMU) for the detection of movements and rotations in 6 degrees of freedom (6DoF). It reflects the full functionality of a triaxial, low-g acceleration sensor and at the same time, it is capable to measure angular rates. Both – acceleration and angular rate – in three perpendicular room dimensions, the x-, y- and z-axis. The BMI088 is designed to meet all requirements for consumer applications such as gaming and pointing devices, HMI and image stabilization (DSC and camera-phone). It also senses tilt, motion, inactivity and shock vibration in cell phones, handhelds, computer peripherals, HMI interfaces, virtual reality features and game controllers. An ASIC converts the output of the MEMS, developed, produced and tested in BOSCH facilities. To provide maximum performance and reliability each device is tested and ready-to-use calibrated.

On the other side, the BME680 - a small, high performance, low power, the 4-in-1 sensor is in charge of the gas, humidity, pressure and temperature measurements. It also features very low power consumption, for example, 3.7 µA is typical at 1 Hz humidity, pressure and temperature measurement mode. It also features a very high accuracy humidity sensor (tolerance ±3% r.H. and hysteresis ±1.5% r.H.), a pressure sensor with only 0.12 Pa RMS Noise (equivalent to 1.7 cm of altitude) and a very low temperature offset drift, and a gas sensor with direct indoor air quality (IAQ) index output system. In principle, the IAQ index output is in an index that can have values between 0 and 500 with a resolution of 1 to indicate or quantify the quality of the air available in the surrounding. It greatly simplifies the categorization of the air quality measurements.

The 13DOF Click Board™ supports the I2C communication interface, allowing it to be used with a wide range of different MCUs. The I2C slave address for the communication can be selected by moving SMD jumpers grouped under the COMM SEL to an appropriate position.

The 13DOF Click Board™ is designed to be operated only with a 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
