Page 3: Introduction
AS5247 Adapter Board 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. Kit Content Figure 1: Kit content Pos. -
Page 4: Board Description
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. Figure 2: AS5247 adapter board P1 connector... -
Page 5: Mounting The As5247 Adapter Board
18mm 30mm 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 Recommendet nominal airgap for the 8 mm magnet = 2 mm. -

Page 8: Operation Case
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. -
Page 9: One Device Spi Mode, Bidirectional - 4 Wire
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... -
