AS5172B Adapter Board
2 Board description
The PCB can be connected to an external programmer or to the AS5172 PSI5 Programming Board, which can be used in combination with the AS5172 Software GUI provided by ams.
P1 is populated with a 1x2 female pin header it is required for the power supply (VDD and GND) and programming interface. (UART-over-PSI5).
All necessary external components C1 (VDD-GND) and C2 (VDD3V3-GND) are already populated to the PCB.

A 8x2.5mm diametric magnet must be placed over or under the AS5172B sensor, and should be centered in 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 a re the best choices to make this part.

4 Operation case
4.1 Connection to AS5172 PSI5 Programming Board
The AS5172B adapter board can be directly connected to the AS5172 PSI5 Programming Board using only two lines (VDD, GND). The voltage supply is coming directly from the programmer which need to be supplied with 12V externally. The UART-over-PSI5 communication is taking place over the VDD line.
