DUILIO F4
The wheel is already made.
Duilio makes it move the right way.
Duilio F4 is designed as a standalone multi-axis motion controller, but it can also be integrated into larger systems.
It interfaces with different control sources — RC receivers, PCs, and single-board computers such as Raspberry Pi, Rock Pi, or Jetson — via USB, GPIO (Raspberry Pi), or the RS485 bus.
It works with any external motor driver using standard 5 V control signals (PWM, DIR, analog, or RC-style), bringing onboard the motion logic that is usually reimplemented every time: ramps, limits, coordination, and failsafe.
Duilio F4 is a motion-control development board that adds safety and coordination on top of external motor drivers.
The firmware is ready to use and configurable with just a few clicks via Duilio Tools, without writing application code.
Supported motor driver interfaces
- PWM + DIR (5 V)
- ENABLE + DIR + PWM (5 V)
- Dual PWM (forward / reverse)
- RC-style PWM (ESC / servo)
- STEP / DIR (speed or position profiles)
- Analog speed (0-5 V)
- Analog speed + direction (0-5 V)
Compatibility depends on the firmware profile; some drivers are already tested, others are under validation.
Why Duilio F4 for motion control?
Driving a motor is easy. Making a machine behave predictably and safely is not. Duilio removes the need to reinvent motion control logic, turning simple motor drivers into real motion controllers - without writing custom application firmware.
If you already have a motor driver, Duilio makes it real motion control. See the full technical features for detailed specs.
What can you build with Duilio F4?
RC vehicles and machines
Cars, boats, tracked vehicles, robotic platforms, remote lawn mowers.
Robots and mechatronic systems
Differential drive, skid-steer, articulated mechanisms, linear actuators.
Servo systems of any power
Turn any motor + any driver into a servo-like axis with limits, ramps and safety.
Duilio works with many external motor drivers and different motor types. If a driver can be controlled via PWM, DIR, analog or RC-style signals, Duilio can manage it. Multiple Duilio boards can be connected together via the RS485 bus, forming an expandable multi-node system for machines with many motors.

Duilio Tools - configuration and diagnostics software
Duilio Tools is the official configuration and debugging software: guided board configuration, parameter tuning without writing firmware code, real-time monitoring and diagnostics.
Designed so that even users without specific programming knowledge can configure the board effectively. Advanced users remain free to work directly with the firmware.
Get involved / Early access program
Duilio F4 is entering the final hardware validation phase. A limited number of pre-production boards will be available for beta testing on real machines.
For the launch phase, the target cost for early access boards is €20-30, depending on configuration and production volume.
