Tinymovr R5 is the new revision of Tinymovr, with better connectivity, broader input voltage range, and smaller footprint!

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, CAN, UART and SPI connectivity.  It can be integrated at the back of the brushless motor for a compact setup.

Features

  • 32-bit Cortex-M4 MCU

    Tinymovr is equipped with a Qorvo PAC5527, a 150MHz 32-bit ARM Cortex M4F, also featuring integrated gate drivers with safety features, power management, differential current sense amplifiers and an advanced ADC.

  • Compact Footprint

    The board measures 36 mm x 40 mm, a footprint compact enough to hide behind a 5005 or larger brushless motor. Reasonable component placement leaves ample room for encoder magnet and wiring.

  • Efficient Power Stage

    The power stage features low RdsOn MOSfets, efficient polymer and ceramic capacitors and optimized layout.

  • Open Source Firmware

    Both the firmware that runs on board, as well as client libraries and apps are and will remain open source.

  • Advanced calibration

    Tinymovr characterizes several motor parameters during the calibration phase, including R & L values, pole pair count, encoder non-linearity and Hall sensor sequence. 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, with Extensive documentation. There is also an Arduino Library available for control of multiple Tinymovrs using CAN bus from Arduino.

  • Trajectory Planner

    Tinymovr includes a real-time trapezoidal trajectory planner, enabling it to generate acceleration- and velocity-limited trajectories, as well as time-limited trajectories for multi-axis synchronization.

  • Hardware Watchdog

    Optional hardware watchdog feature to safely disable power to the motor should a communication error occur

  • 20kHz Control loop

    Tinymovr uses 20kHz for both PWM and control loop rate, enabling inaudible operation, wide control bandwidth, and conservative resource usage.
