StingBee Stellar 32bit ESC AM32 V1 80A — High-Performance Choice for FPV Drones

The StingBee Stellar 32bit ESC AM32 V1 4in1 from StingBee (Product ID: 18980) is a reliable and powerful brushless ESC designed for demanding drone, racing, and freestyle applications. It combines open-source AM32 firmware, a modern processor, and well-engineered hardware for maximum control precision and stable operation under heavy loads. This product belongs to the category: Drones & Quadcopters > Stacks (FC+ESC).

Key Features

• Firmware: AM32 (open-source firmware) — flexible settings, allowing fine-tuning to your needs.
• Processor: STM32G071 — powerful controller for fast signal processing and stable ESC operation.
• Max Current: 80A — suitable for powerful motors and aggressive piloting.
• Input Voltage: Compatible with 2–8S LiPo, making the ESC versatile for various battery configurations.
• Design: 4in1 form factor for compact mounting inside the frame.
• Mounting Dimensions: 30.5x30.5x4 mm; overall dimensions: 46x50x8 mm — compact size for easy integration.

Supported Protocols and Telemetry

StingBee Stellar supports modern motor control protocols: DShot 300/600/1200, Bidirectional DShot (two-way communication for RPM data feedback), as well as PWM, Oneshot125, and Multishot. The presence of telemetry allows real-time monitoring of ESC status and optimization of flight behavior, which is especially important for competitions and quick adjustment of settings.

Reliability and Protection

The device is equipped with two TVS diodes for overvoltage protection, significantly increasing resistance to peak stresses in the power system. 14 1210 22µF capacitors are used to smooth ripples and ensure stable voltage. Optimized PCB layout with reinforced copper traces withstands high current loads and reduces internal resistance, increasing efficiency and reliability under sustained loads.

Cooling and Construction

The ESC is equipped with an efficient heatsink for MOSFET cooling, preventing overheating and extending component lifespan. The 4in1 design allows all channels to be compactly placed on a single board, simplifying installation and connection within the drone frame. Reinforced traces and a well-thought-out board topology ensure stable operation even at peak currents.

The combination of Bidirectional DShot support, a wide range of protocols, overvoltage protection, a powerful STM32G071 controller, 80A peak support, and compact mounting dimensions makes the StingBee Stellar ESC AM32 V1 an optimal choice for pilots seeking high control precision, reliability, and ease of integration into various frames and configurations.
