HTCC-AB02 recommended pins to power up an external sensor

Hi everyone!

I would like to power an RS232 range sensor 3.3V 49mA (max) from my HTCC-AB02 board. Is there any recommended pin to power the sensor? Vdd? Vext? I will power the HTCC board by Vin with 5V, and I would like to take advantage of the board noise reduction circuit.

Best regards.

Both VDD and Vext are fine.
