ams AS5047D Adapter Board
Product Information
The AS5047D adapter board is a small PCB designed for testing and evaluating the AS5047D magnetic position sensor. It eliminates the need for building a test fixture or designing a custom PCB. The adapter board can be connected to an external microcontroller or to the Universal Connector Board (AS5xxx-UCB) in combination with a NI USB-8451 box and the provided LabVIEW software.
Kit Content
The kit includes the following items:
- AS5047D-TS_EK_AB (Adapter board)
- AS5000-MD6H-2 (Diametric Magnet, D6x2.5mm, NdFeB, Bomatec AG)
Product Usage
Board description
The PCB can either be connected to an external microcontroller or to the Universal Connector Board (AS5xxx-UCB) in combination with a NI USB-8451 box and our provided LabVIEW software.
P1 has to be populated with a 2×8 pin header and is required for power supply as well as SPI, ABI, UVW/PWM interfaces.
The connector JP1 allows to select between 5V or 3.3V operation.
Depending on the supply voltage either R1 or R2 has to be populated. For 5V operation R1 and for 3.3V operation R2 has to be populated.
Mounting the AS5047D Adapter Board
A 6×2.5mm diametric magnet must be placed over or under the AS5047D sensor, and should be centered on the middle of the package with a tolerance of 0.5mm. The airgap between the magnet surface and the package should be maintained in the range 0.5mm to 3mm. The magnet holder must not be ferromagnetic. Materials as brass, copper, aluminum, stainless steel are the best choices to make this part.

Operation case
One device SPI mode, unidirectional – 3 wire
The AS5047D 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 AS5047D 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 AS5047D 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 AS5047D the MOSI connection is required.
