Duet 3 Magnetic Encoder

[Diste]

Hello everyone!

These days I came across the Duet 3 Magnetic Encoder, and I’m considering using it in my project: a four-wheeled robot. Each wheel is driven by a NEMA17 stepper motor.

Since I’d prefer not to use a multiplexer (MUX), I was wondering:
Is this encoder suitable for projects with multiple stepper motors without requiring a MUX?

Thanks in advance!

@Diste I am not sure what a multiplexer would be used for. Our magnetic encoder would communicate with the microcontroller in your system using SPI. You can connect multiple encoders to a single SPI bus but each one needs its own CS signal from the microcontroller. So to monitor all 4 wheels you would need the standard three SPI lines to/from the MCU (MOSI, MISO and SCLK) plus 4 CS signals to the encoders to select which one you are communicating with.

@dc42 Thank you so much for clarification, this is exactly what I was looking for!
