moteus r4.11 is a compact BLDC motor controller designed by mjbots (Josh Pieper) for dynamic robotics. Converts a hobby brushless motor into a high-performance servo actuator. Integrates drive electronics, a 170 MHz STM32G4 32-bit microcontroller, an absolute magnetic encoder (¼" magnet included), and a fast 5 Mbps CAN-FD interface.
Specifications: 10–44 V input (≤10S LiPo), 100 A peak phase current, 12 A continuous (no cooling) / 32 A (with heat management), 900 W peak electrical power at 30 V. Dimensions 46 × 53 mm, mass 14.2 g. Control rate 15–30 kHz, PWM 15–60 kHz, max electrical frequency 2 kHz.
Power and data can be daisy-chained via XT30PW-M and JST PH-3 connectors. Firmware is open-source (Apache 2.0, GitHub: mjbots/moteus). Used in the mjbots quad A1 quadruped robot. Developer kit available with motor, CAN-FD adapter, and power supply.

Electronic Speed Controller (ESC) · serves as: Motor Control, Closed-Loop Drive Control, Joint Actuation.
