Tinymovr is an affordable servo motor controller for hobby brushless motors. It allows you to operate a hobby brushless motor in position, velocity and torque modes, using Field Oriented Control (FOC). Tinymovr is highly integrated incorporating a 32-bit ARM Cortex M4F microcontroller, power electronics, integrated magnetic angle sensor, and CAN and UART connectivity. It can be integrated at the back of the brushless motor for a compact setup.

- Tinymovr R3.4
- Diametrically Magnetized NdFeB magnet
We suggest the CANine CAN Bus to USB Type C Adapter together with Tinymovr. You may also need a Wire Pack to hook things up.
Features
32-bit Cortex-M4 MCU
Tinymovr is equipped with a Qorvo PAC5527, which is a 150MHz 32-bit ARM Cortex M4F microcontroller with floating point unit, 32kB RAM and 128kB Flash. PAC5527 also features integrated gate drivers, power management and current sensing.
Open Source Firmware
Both the firmware that runs on board, as well as client libraries and apps are and will remain open source.
Compact Footprint
The board measures 40x40mm, a footprint compact enough to hide behind a 5005 or larger brushless motor. Reasonable component placement leaves ample room for encoder magnet and wiring.
20kHz Control loop
Tinymovr uses 20kHz for both PWM and control loop rate, enabling inaudible operation, wide control bandwidth, and conservative resource usage
Advanced calibration
Tinymovr characterizes several motor parameters during the calibration phase, including R & L values, pole pair count, and encoder non-linearity. Corrections to encoder readings and current controller gain tuning are then performed automatically.
Easy to setup and use
Tinymovr Studio is a high level Python client that allows easy motor control through an iPython interface. Extensive documentation is available
