AS5247 Adapter Board
Product Information
The AS5247 adapter board is a small PCB designed for testing and
evaluating the AS5247 magnetic position sensor. It eliminates the
need for building a test fixture or designing a custom PCB. The
board can be connected to an external microcontroller or the
I&P USB Box using the 5-pin dual row connector P1. P1 provides
power supply and SPI interface access, while P2 can be populated
with a 2×8 pin header for ABI and UVW interfaces.
Kit Content
The kit includes:
- AS5247-MF_EK_AB (Adapter board)
- AS5000-MD8H-1 (Diametric Magnet, D8x2.5mm, NdFeB, Bomatec
AG)
Mounting Instructions
To mount the AS5247 adapter board:
- Place an 8 x 2.5 mm diametric magnet over or under the AS5247
sensor. - Center the magnet on the middle of the package with a tolerance
of 0.5 mm. - Maintain an airgap between the magnet surface and the package
in the range of 0.5 mm to 3 mm.

2 Board description
The PCB can either be connected to an external microcontroller, or to the I&P USB Box using the 5pin dual row connector P1. P1 is already populated and gives access for power supply as well as SPI interface. P2 has to be populated with a 2×8 pin header and can be used for ABI and UVW interfaces.

2.1 Mounting the AS5247 adapter board
Figure 3: Mounting and dimensions
A 8 x 2.5 mm diametric magneticed magnet must be placed over or under the AS5247 sensor, and should be centered on the middle of the package with a tolerance of 0.5 mm. The airgap between the magnet surface and the package should be maintained in the range 0.5 mm to 3 mm.
Recommendet nominal airgap for the 8 mm magnet = 2 mm.
Recommendet nominal airgap for the 6 mm magnet = 1.5 mm.
The magnet holder must not be ferromagnetic. Materials as brass, copper, aluminum, stainless steel are the best choices to make this part.

AS5247 Adapter Board
4 Operation case
4.1 One device SPI mode, unidirectional 3 wire
The AS5247 adapter board can be directly connected to an industry standard SPI port of a microcontroller. The minimum connection requirements for unidirectional communication between the microcontroller and the AS5247 are MISO, CLK, CSn. In this case the MOSI pin is tied to VDD wich will result in reading only the 14-bit Angle Register (0x3FFF). See AS5247 datasheet register table, register 0x3FFF.

4.2 One device SPI mode, bidirectional 4 wire
If it’s needed to read other registers than the Angle Register (0x3FFF) or to write to registers of the AS5247 the MOSI connection is required. Figure 6: One device SPI mode, bidirectional 4 wire
