Configure Controller

Heads up

OctoMY™ ships exactly one hardware controller — Fixo. The earlier multi-controller selector (Fixo / Fluxo / Servotor32) was retired in 2026. Setting up a controller now means setting up Fixo.

See Configure Fixo Controller for the current step-by-step guide.

If you're looking for background on why we collapsed to one controller, the Why Fixo explanation covers it.

What used to be here

This page once described two parallel setups: flashing a generic ArduMY firmware to your Arduino, and selecting a controller binding (ArduMY, Servotor32, Fixo) inside the Agent. Both are gone. ArduMY's runtime-configurable firmware was replaced by Fixo's compile-and-flash workflow; Servotor32 was retired with the rest of the multi-controller plumbing.

Concretely, that means:

• There is no separate "controller selection" step. Open the Fixo Studio and start designing a preset.
• There is no pre-built generic firmware to flash by hand. The Agent compiles a purpose-built binary for your exact hardware and flashes it for you.
• There is no controller-type setting in the Plan. The controller is implicit; the preset is what varies.

If you're following an older tutorial that mentions "ArduMY firmware" or "Servotor32 binding", that text is out of date — jump to Configure Fixo Controller instead.
