Bosch Sensortec BHA260 Shuttle Board GENERAL DESCRIPTION Bosch Sensortec’s BHA260 shuttle board is a PCB with the BHA260, a smart sensor sub with integrated acceleration sensor, mounted on it. In addition to the BHA260, the board includes  on M2 master interface (configured as SPI):  a BMG250 Gyroscope  on M3 master interface (configured as I2C):  a BME280 environmental sensor (p, rH, T)  a BMM150 magnetometer  an AK09915 magnetometer connected to the BHA260. Additional sensors can be connected to the M3 I2C bus, using connector J6. The shuttle board allows easy access to pins of the smart sensor hub via a simple socket. The shuttle board comes pre-mounted on a level-shifter board, which allows the PCB stack to be directly plugged into Bosch Sensortec’s advanced development tool (application board).

Do not connect the shuttle board directly to the application board, as this can lead to severe damage of the shuttle board and its components.
