GENERAL DESCRIPTION
The Bosch Sensortec BHA250 shuttle board is a PCB with
the BHA250 Smart Sensor Hub mounted on it.
Additionally, it includes up to four external magnetometers, an
AKM09911, AKM09912, BMM150, and a YAS532 which can be
connected to the BHA250 using the available jumpers on the
PCB. All magnetic sensors are enabled by default (Jumper J15
can be used to switch off the power supply of individual sensors,
in case this is needed). Additional sensors can be attached to
the shuttle board, using the TFR-Card connector interface (J10)
provided on the board, next to the jumpers.
The shuttle board allows easy access to the sensor’s pins
via a simple socket. As all Bosch Sensortec sensor shuttle
boards have identical footprint, they can be plugged into Bosch
Sensortec’s advanced development tools (e.g. the Development
Board or Application Board).
