Product overview
NanChang ChangKong Technology Co., Ltd’s CKESC STONE 150A-M is a brushless UAV electronic speed controller with PWM control and serial telemetry. It measures 92*40.4*20.9mm and weighs 155g including wiring. Its connections comprise red/black silicone power leads, black silicone three-phase motor leads, a gray signal cable and a separate data feedback ribbon cable. Shielded signal wiring reduces interference, while optically isolated signal input and output interfaces provide interference isolation. The controller has no BEC.
The default firmware is the timing-adjustment version, with a fixed version optional and maximum-power mode available to enable. Motor rotation direction can be set through software. Continuous operation is rated at 100A with specified cooling, while 150A operation is limited to 3 seconds. Standard ingress protection is IP54, with IP67 available by customization. Low-voltage protection is disabled by default. Overtemperature and signal-loss protection reduce output, while a motor stall at high throttle may damage the ESC.

| Input signal level | 3.3~5V |
| Temperature protection threshold | 125°C |
| Control communication | PWM |
| Low-voltage protection | Optional low-voltage protectionDisabled by default; enabling available by customization. |
| High-voltage protection | Prevents motor startupWhen supply voltage exceeds the permitted value. |
| Startup protection | Limits starting current and automatically retries startupWhen startup fails. |
| Stall protection | Attempts to restart the motorIf the motor stalls during operation; a stall at high throttle may damage the ESC. |
| Overtemperature protection | Gradually reduces maximum output power, potentially down to 40% of full-throttle powerAbove 125°C; original power is restored after temperature falls. |
| Overcurrent protection | Limits peak current to the limiting value |
| Overload protection | Limits maximum throttle to protect the propulsion systemWhen excessive motor load is detected. |
| Signal-loss protection | Progressively reduces output; rapidly lowers throttle below 50% within 1~2 seconds, then slowly reduces throttle until shutdownAfter signal loss lasting 200ms. |
| Real-time telemetry | Supply voltage, motor speed, current, ESC temperature and debugging dataVia serial output. |
| Firmware configuration | Maximum-power mode can be enabledDefault firmware is the timing-adjustment version; a fixed version is optional. |
