Redhobby AM32 30A Bidirectional Brushless ESC for 2-4S LiPo - 6V 2A UBEC Multi-Platform Speed Controller for RC Multicopter, Airplane, Car, and Boat
The Redhobby AM32 30A Bidirectional Brushless Electronic Speed Controller brings the open-source AM32 firmware platform to a versatile, multi-platform speed controller rated at 30A continuous on a 2-4S LiPo input. AM32 is a community-developed brushless ESC firmware designed as a capable alternative to BLheli_S, offering active development, bidirectional DSHOT support, and extended configurability through the AM32 configurator interface. This makes the ESC well-suited for RC multicopters and fixed-wing aircraft running Betaflight or ArduPilot-based flight controllers, as well as surface and marine platforms where bidirectional motor control and digital signal protocol support are required from a single compact unit.
A distinguishing feature of this ESC over comparable units in the 30A class is the integrated UBEC output rated at 6V / 2A, a step up from the standard 5V / 500mA or 5V / 1A BEC commonly found in this current class. The 6V / 2A UBEC delivers sufficient regulated power for receivers paired with higher-voltage digital servos, onboard FPV electronics, or multiple servo channels without requiring a separate voltage regulator module. Bidirectional operation enables forward and reverse motor rotation without manual phase-swap rewiring, supporting RC car and boat applications where reversing drive direction through the transmitter is a standard operational requirement. The AM32 firmware's support for DSHOT digital protocols, RPM telemetry, and extended motor timing parameters makes this ESC a capable choice for builders who want open-source firmware flexibility across a diverse range of RC platforms.
Key Features
- Firmware Platform: AM32 open-source brushless ESC firmware with PC-based configuration via AM32 Configurator.
- Continuous Current Rating: 30A continuous with short-burst headroom for high-throttle demand across all supported platforms
- Battery Compatibility: 2-4S LiPo (7.4V-14.8V) for flexible voltage selection across multicopter, airplane, car, and boat builds
- Bidirectional Motor Control: Electronic forward and reverse rotation without manual phase-swap rewiring for car and boat applications
- Integrated UBEC Output: 6V / 2A regulated UBEC powers receivers, digital servos, and onboard FPV electronics without a separate regulator
- Digital Signal Protocol Support: DSHOT150, DSHOT300, and DSHOT600 alongside OneShot and standard PWM for broad flight and drive controller compatibility
- RPM Telemetry: Supports Betaflight and ArduPilot RPM filtering and motor health monitoring when paired with compatible flight controllers
- AM32 Configurator Support: Per-motor parameter adjustment, including timing advance, demag compensation, and throttle calibration via PC interface
- Multi-Platform Compatibility: Suitable for RC multicopters, fixed-wing airplanes, ground vehicles, and surface watercraft from a single ESC unit
- Active Freewheeling: Reduces heat build-up and improves power efficiency during partial-throttle and transition phases
- Low-Voltage Protection: Configurable per-cell cutoff prevents LiPo over-discharge across 2S to 4S configurations
Thermal Shutdown: Automatic over-temperature protection safeguards the ESC and motor under sustained high-load conditions.
