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.
