StingBee ESC 12S 100A

Description StingBee ESC 12S 100A

StingBee 12S 100A AM32 Electronic Speed Controller

The StingBee 12S is a high-performance ESC designed for FPV and industrial drone applications where maximum power, precision, and reliability are required. It runs on AM32 open firmware and is powered by a STM32G071 microcontroller, ensuring fast response, stable operation, and compatibility with modern control protocols.

It supports 4S to 12S LiPo input, delivering 100A continuous current and up to 140A peak. It uses high-efficiency low-resistance MOSFETs combined with dedicated high-power MOSFET drivers to fully drive each phase for maximum performance with minimal heat buildup.

The board is equipped with 11 high-quality 1210 ceramic capacitors, ensuring stable power filtering at high loads. A high-precision current sensor provides reliable telemetry feedback. Multiple control and telemetry protocols supported by AM32 firmware are available, including bidirectional DShot.
