Note: Specifications within this document are subject to change without notice.
2.2 Power
The board can be powered either via a USB cable or an Arduino board. In the former
case a jumper should connect pins number 2 and 3 of the power source selection pins.
In the latter case a connection between pins 1 and 2 are required.
2.3 BMF055 Shuttle Board
The shuttle board is a small circuit board with a BMF055 chip mounted on it. In addition
to the sensor it includes the decoupling/filtering capacitors, reset pull-up resistor
(RESETN) and a 32 KHz crystal and load capacitors.
Figure 3 - BMF055 Shuttle Board
2.4 Arduino
BMF055 breakout board can be connected to an Arduino board as a shield. The male
connectors at the bottom side provide this possibility. As shown in Figure 4 further
shields can also be connected to the female connectors.
Figure 4 - Connection to Arduino UNO and an Arduino shield
2.5 Customization
The only connections to the Arduino and Shuttle board connectors on the breakout
board are VDD and GND. The other pins are left unconnected so that users can
customize how they desire. There are the two sets of male connectors available on the
board: The inner set (Number 5 in Figure 2) is connected to the shuttle board pins in a
one-to-one manner and the outer one (Number 6 in Figure 2) is connected to the
Arduino pins in the same manner. These connectors can be used for the customization.

3 Necessary Connections
3.1 Shuttle board
The BMF055 shuttle board should be plugged in to the socket on the breakout board
in a way that pin number 1 of the shuttle is connected to the pin number 1 of the socket.
3.2 Power
Either a USB connection or a connection to an Arduino board is required to provide
power for the board.
3.3 Power jumper
If the breakout board’s power is provided by an Arduino board the jumper J11 must
connect pins number 1 and 2.
Otherwise, if a USB cable provides the power, the jumper J11 must connect pins
number 3 and 2.
3.4 Programmer/ debugger connection
To program the microcontroller in BMF055 a programmer/ debugger is required. The
board has a standard JTAG connector to for this purpose.

6 BMF055 Shuttle Board
Bosch Sensortec BMF055 shuttle board is a PCB with a BMF055 Orientation Sensor
mounted on it. It has the required decoupling capacitors, an external 32 KHz crystal
and its load capacitors and allows easy access to the sensors pins via a simple socket.
The shuttle board can be plugged into Bosch Sensortec development tools, BMF055
Breakout Board, custom designed boards or breadboards.
6.1 Power
BMF055 has two distinct power supply pins:
VDD is the main power supply for the internal sensors
VDDIO is a separate power supply pin used for the supply of the MCU and the
digital interfaces
The voltage supply range for VDD is 2.4V to 3.6V and for VDDIO is 1.7V to 3.6V.
For the switching sequence of power supply VDD and VDDIO it is mandatory that VDD
is powered on and driven to the specified level before or at the same time as VDDIO is
powered ON. Otherwise there are no limitations on the voltage levels of both pins
relative to each other, as long as they are used within the specified operating range.
6.2 Programming/ Debugging
Programming and debugging of the chip is done Serial Wire Debug Interface available.
Any debugger that supports the interface can be used. (e.g Atmel SAM-ICE)

6.3.1 Internal Signals
The internal signals are the ones that connect the MCU to the three sensors:
accelerometer (BMA280), magnetometer (BMM150) and gyroscope (BMG160). The
internal signals are as follows:
SPI MISO: the MISO signal of the SPI bus that connects the MCU and the
three sensors
SPI MOSI: the MOSI signal of the SPI but that connects the MSU to the three
sensors
SPI SCLK: the clock signal of the SPI but that connects the MSU to the three
sensors
SPI CS1: the chip select signal connected to accelerometer and
magnetometer
SPI CS2: the chip select signal connected to gyroscope
INT1: interrupt signal connected to INT1 pin of accelerometer and gyroscope
INT2: interrupt signal connected to INT2 pin of accelerometer and gyroscope
Please note that, MCU pins connected to the interrupt signals may be used as GPIOs
only if the corresponding sensor interrupt is not configured.
For more information regarding the internal signals please refer to BMF055 datasheet.
