Missing Encoder Output Type & Encoder Output Ranges In Datasheet, SKU: FIT0186
duytruongcute 2026-08-23 23:34:28 134 Views2 Replies Hi, I’m using this motor’s quadrature encoder with an ESP32. Are the outputs of this motor push-pull, open-collector, or open-drain? Also, is the maximum output 5V or 3.3V? I'm trying to connect it to ESP32 but its GPIO only accepts 3.3V. Do I have to level shift the outputs when connecting? Thanks.
The encoder is said to be 5V. You'd better not try using your 3.3V GPIO port.
Jason.Miao The wiki lists encoder operating voltage as 5V but doesn't say if the outputs are push-pull or open-collector.
Quick way to check: power the encoder and measure the A/B pins with a multimeter while the motor is still. If you see ~5V sitting there it's push-pull. If they're floating near 0V it's likely open-collector.You can give it a try and share your results. Then we can see what the actual situation is like.
