Adapter PCB Operation Manual
If you use the Adapter PCB as external encoder for the AS5043 demoboard with an extension cable or experience
data transmission errors, it is requested to configure the Adapter PCB for 3.3V supply voltage.
9.1.1
Perform the following modifications:
* If longer cables are used, a pull-down resistor at the DO line of 22k - 56k Ohms is recommended to discharge
the signal between data transmissions and no static voltage is built up.

Modifications to operate the adapter board at 3.3V
disconnect the 5V supply between Demoboard and Adapter PCB: remove or cut off pin "+5VUSB" at the
bottom of the AS5043 demoboard
connect pins "3V3" and "5V" on the Adapter PCB. Ideally, connect the pins right at the bottom of the
7pin female connector with a piece of wire or solder joint.
you may also remove the 78L05 voltage regulator from the Adapter PCB to prevent accidental damage
of the IC when an input voltage is applied to the regulator (and the 5V output is fed to the VDD3V3
supply pin)
