Introduction
The AS5247 adapter board is a small PCB allowing simple and quick testing or evaluation of the
AS5247 magnetic position sensor without the need to build a test fixture or design an own PCB.

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 2x8 pin header and can be used for ABI and UVW interfaces.

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.

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.

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.
