FIT0185 encoder A/B output type and voltage level

Hello DFRobot Support,

I’m using your 12V DC Motor 83rpm w/ Encoder (SKU: FIT0185) with an Arduino Portenta X8 (3.3V logic).

Could you please confirm:

1)Is the encoder output A/B open-collector/open-drain or push-pull ?

2)What is the A/B output voltage level (HIGH level) when powered at 5V?

3)Do A/B require external pull-up resistors? If yes, recommended value (e.g., 4.7k/10k)?

Regards,

Vishal Pawar
