What it does
- Provides full hardware designs for the moteus controller boards in four variants: r4.11, c1, n1 and x1.
- Includes firmware for the brushless motor controller.
- Offers client-side software and diagnostic tools for working with the servo.
- The r4.11 variant runs on an STM32G4 CPU with a 15-30kHz control rate and 15-60kHz PWM switching rate.
- The r4.11 variant has 5Mbps CAN-FD communications.
- Warns that the project includes moderately high power electronics and is not just a software project.
