Bosch Sensortec BHI260 Shuttle Board GENERAL DESCRIPTION Bosch Sensortec’s BHI260 shuttle board is a PCB with the BHI260, a smart sensor hub with integrated IMU sensor, mounted on it. In addition to the BHI260, the board includes  on M2 master interface (configured as I2C):  a BME280 environmental sensor (p, rH, T)  a BMM150 magnetometer  an AK09915 magnetometer on QSPI interface:  a W25Q32FWSSI 4M-Byte flash memory connected to the BHI260. Addition sensors can be connected to the M3 I2C bus, using connector J8. 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.
