Introduction
The RoboMaster C615 Brushless Motor Speed Controller offers precise and responsive motor
control and uses a DJI-designated 32-bit motor driver, allowing for a maximum main frequency
of 100 MHz and a maximum output PWM frequency of 48 kHz. Additionally, the speed controller
also features a stall protection function that automatically cuts off the phase currents when the
motor is stalled, preventing the speed controller from being damaged. The anti-static design
of the speed controller ensures a high level of reliability and stability. This speed controller is
compatible with the RoboMaster Snail 2305 Brushless DC Motor, which, when combined, creates
a high-performance propulsion kit.
