AS5046 12-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
Adapter PCB Operation Manual
The demoboard however, runs at 3.3V supply voltage. The adapter PCB is configured for 5V supply voltage. Connecting
both boards without modifications will not harm any of the boards, but may lead to data transmission errors due to the
different digital levels, especially when an extension cable is used between demoboard and Adapter PCB.
If you use the Adapter PCB as external encoder for the AS5046 demoboard with an extension cable or experience data
transmission errors, it is requested to configure the adapter PCB for 3.3V supply voltage.

Perform the following modifications:

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 AS5046 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)
