The 3D magnetic sensor TLV493D-A1B6 offers accurate three-dimensional sensing with extremely low power consumption in a small 6-pin package. With its magnetic field detection in x, y, and z-direction the sensor reliably measures three-dimensional, linear and rotation movements. Applications include joysticks, control elements (white goods, multifunction knops), or electric meters (anti tampering) and any other application that requires accurate angular measurements or low power consumptions. The integrated temperature sensor can furthermore be used for plausibility checks.
Key features are 3D magnetic sensing with a very low power consumption during operations. The sensor has a digital output via 2-wire based standard I2C interface up to 1 MBit/sec and 12 bit data resolution for each measurement direction (Bx, By and Bz linear field measurement up to +-130mT).

- Supply voltage is typ. 3.3 V, please refer to the TLV493D-A1B6 datasheet for more details about maximum ratings
- Pin out on top (head) is directly connected to the pins of the TLV493D-A1B6 sensor
- The break out board is compatible with Infineon’s offer of joysticks, rotation knobs and additional supplies for the 3D magnetic sensor portfolio
- If head is broken off, only one capacitor is connected to the TLV493D-A1B6 sensor
- Software compatible with Arduino and library fully integrated into the Arduino IDE
- Sensor has different I2C addresses, please refer to the User Manual for more information
- Sales Name S2GO_3D-SENSE_TLV493D and OPN S2GO3DSENSETLV493DTOBO1
Ensure that no voltage applied to any of the pins exceeds the absolute maximum rating of 3.5 V
The Shield2Go form factor of the Shield2Go evaluation board is directly compatible with the XMC2Go board
- Stack the TLV493D-A1B6 3DSense Shield2Go board on top of the XMC2Go as shown in the picture
- The additional pin on the left-top side (designated with NC) is left floating
- Using the XMC-for-Arduino Arduino integration, the Arduino library for the TLV493D-A1B6 can be directly used
Open one of the examples for the TLV493D-A1B6 from File – Examples and select as board XMC1100 XMC2Go. Connect the stacked boards to the PC and press the Upload button. Select the related COM port from Tools – Port and open the serial monitor with the set baud rate (see sketch/code with Serial.begin(<BAUDRATE>);)
The TLV493D-A1B6 has a maximum rating of 3.5 V on any pin. Third party boards with 5 V logic, e.g. the Arduino Uno, cannot be connected to the TLV493D 3DSense Shield2Go board directly. Even if the power is connected to the 3.3 V pin, the interface lines, e.g. SDA/SCL, will still be driven by 5 V.
Please use appropriate level shifting for these boards.
