Introduction
RAB1-SENSORFUSION is an Arduino shield adapter for the environment and inertial sensors from Infineon, Sensirion and Bosch evaluation and prototyping. It is powered via Arduino headers with a single 3.3V supply. No overvoltage, polarity protection or voltage regulator included. All the sensors are configured to work with the I2C interface only, except the DPS310XTSA – it can be used with SPI as well as with I2C [I2C is default]. All the I2C addresses are fixed for all the sensors and cannot be reconfigured. Every particular sensor could be disconnected from the power supply and I2C circuits by unsoldering solder bridges. The interrupts of BMI270 and BMP581 could be connected to almost any Arduino pin using solder bridges configuration or simply using wires [the holes at every pin are provided for that purpose].
Features
- DPS310 – Infineon’s digital XENSIVTM barometric pressure sensor.
- BMP581 – Bosch’s digital pressure sensor.
- SGP40 – Sensirion’s indoor air quality sensor for VOC measurements.
- BME688 – Bosch’s digital low power gas, pressure, temperature and humidity sensor with AI.
- SHT41 – Sensirion’s high-accuracy and low power relative humidity and temperature sensor.
- BMI270 – Bosch’s 6-axis, smart, low power inertial measurement unit.
- I2C and SPI interface via Arduino compatible ADAM-TECH connectors.
- A Keystone Electronics Test Point connector for a ground signal.

Fuses
The RAB1-SENSORFUSION board has only one 2A fast acting fuse F1 in a 1206
package; Part No: CC12H2A-TR „Eaton“.
Changing the fuses or solder bridges
The SMD „Chipping Tool“ is recommended to use for SMD solder bridges or fuses
soldering on the RAB1-SENSORFUSION development board.

Legal Disclaimer
The evaluation board is for testing purposes only and, because it has
limited functions and limited resilience, is not suitable for permanent use
under real conditions. If the evaluation board is nevertheless used under real
conditions, this is done at one’s responsibility; any liability of Rutronik is
insofar excluded.
