+===== Schematic=====
+Bosch Sensortec expansion deck V2 {{:undefined:bosch_v2_schematics.pdf|schematic}}
+===== Setting Up =====
+If not already done create config.mk in tools/make from [[https://github.com/bitcraze/crazyflie-firmware/blob/master/tools/make/config.mk.example|config.mk.example]] and add the following line:
+<code make>SENSORS = bosch</code>
+Before make you may want to adjust which sensor should be used as gyroscope /accelerometer. This can be done by changing
+<code c>
+static uint8_t gyroPrimInUse =          SENSORS_BMI055;
+static uint8_t accelPrimInUse =         SENSORS_BMI055;
+</code>
+in [[https://github.com/bitcraze/crazyflie-firmware/blob/master/src/hal/src/sensors_bosch.c#L47|sensors_bosch.c]] to any of the [[https://github.com/bitcraze/crazyflie-firmware/blob/master/src/hal/src/sensors_bosch.c#L37|available sensors]] which fit as gyroscope respectively accelerometer.
+Now you are ready to make the firmware and flash it on your crazyflie.
+For evaluation purposes you might want to log sensors data which can be done with help of the [[projects:crazyflie2:expansionboards:microsd|Micro SD expansion deck]].
