Product overview
The CKESC STONE 200A-M from NanChang ChangKong Technology Co., Ltd controls brushless UAV motors through PWM input. Its 104 × 56 × 24.5mm body weighs 247g including wiring, providing concrete dimensions for installation planning. The wiring comprises 150mm red/black 10AWG silicone power leads, 100mm black 10AWG silicone three-phase leads, a 550mm gray 24AWG signal cable and an 80mm data feedback cable. Signal inputs and outputs use optical isolation, while the shielded signal cable reduces interference. No BEC is included, which matters when planning power distribution.
The supplied firmware supports timing adjustment, with a fixed version optional and maximum-power mode available to enable. Motor direction can be set through software, and serial output provides supply voltage, motor speed, current, ESC temperature and debugging data. Continuous operation is rated at 130A with specified cooling; 200A is limited to three seconds. Standard ingress protection is IP54, with IP67 available by customization. Low-voltage protection is disabled by default. Thermal protection reduces power above 125°C, and a motor stall at high throttle can damage the controller despite its restart protection.

| Input signal level | 3.3~5V |
| Temperature protection threshold | 125°C |
| Communication method | PWM |
| Operating ambient temperature | -20~+65°C |
| Low-voltage protection | Optional customized low-voltage protectionDisabled by default; enabling requires customization. |
| High-voltage protection | Prevents motor startupWhen supply voltage exceeds the permitted value. |
| Startup protection | Limits starting current and automatically retries startupFollowing an unsuccessful start. |
| Stall protection | Attempts to restart the motorIf the motor stalls during normal operation; a stall at high throttle may damage the ESC. |
| Overtemperature protection | Gradually reduces maximum output power, potentially down to 40% of full-throttle powerWhen temperature exceeds 125°C; original power returns after temperature falls. |
| Overcurrent protection | Limits peak current to prevent exceeding the limiting value |
| Overload protection | Limits maximum throttle to protect the propulsion systemWhen excessive motor load is detected. |
| Signal-loss protection | Progressively reduces output power, rapidly lowers throttle below 50% within 1~2 seconds, then slowly reduces throttle until shutdownAfter signal loss lasting 200ms. |
| Firmware configuration | Timing-adjustment firmware supplied by default; optional fixed firmware and an enableable maximum-power modeDefault firmware is the timing-adjustment version; a fixed version is optional. |
