Adapter PCB Operation Manual
6 AS5043 Adapter PCB Schematic:
For normal operation, the only required external components are the buffer cap at VDD3V3 (C4) and the pull-down
resistor for CSn (R7; 0Ω….4k7).
The PCB operates at several power supply levels:
Power Supply options:

voltage
3,0….3,6V
4,5….5,5V
7,5…20V
7,5…20V
*) if already installed, external voltage regulator can be left installed.
