Raptor Power 12S 4in1 ESC
A 6S–12S four-in-one ESC for drones. Each motor has its own processor and gate driver, with current, voltage and temperature telemetry.
Overview
The Raptor Power 12S 4in1 ESC drives four brushless motors from one board. It runs on 6S to 12S LiPo. Each motor has its own STM32G071 processor, its own DRV8300 gate driver and six 100 V MOSFETs. Motor control is sensorless, using back-EMF zero-crossing detection, and the firmware target is AM32.
It tells the flight controller what is happening on board. Current, voltage and temperature go out on one UART telemetry line, and there is an analog current output as well. It takes DShot150/300/600 and standard PWM inputs, depending on the firmware.
There is no hardware overcurrent cut-off: set the current limit in the flight controller or the ESC firmware. The board has no BEC. It needs two external low-ESR capacitors (470–1000 µF, 63 V) within 3 cm of the battery pads. For high continuous current, fit a heatsink on the MOSFET side and keep propeller airflow over the board.
Current ratings, weight and operating temperature are being measured on the prototype. We will publish them when testing is complete.
