Tinymovr is an affordable motor controller for precise control of 3-phase brushless motors. Tinymovr is highly integrated incorporating an advanced MCU (Qorvo PAC5527), compact power stage, integrated absolute angle encoder (MPS MA702) and CAN and UART connectivity. Tinymovr can operate in Torque, Velocity or Position modes, using Field Oriented Control (FOC). It can be integrated at the back of the brushless motor for a compact setup.
Features at a glance
Cortex M4 Microcontroller
Tinymovr is equipped with a Cortex M4F microcontroller with floating point unit, 128kB Flash and integrated gate drivers, power management and current sensing.
Open Source Firmware
Both the firmware that runs on the boards, as well as client libraries and apps are and will remain open source under the GNU GPL v3.
Compact Footprint
The board measures 40x40mm, a footprint compact enough to hide behind a 5010 or larger brushless motor. Reasonable component placement leaves ample room for encoder magnet and wiring.
