Description:Plug-and-Play Firepower: Designed for easy integration into standard V2 gearboxes (minor housing modifications may be required for some models). Dual DirectFET Design: Supports up to 300A burst current and 160A braking current, providing unparalleled motor control and performance stability. Intelligent Battery Detection and Protection: Automatically detects the number of battery cells and activates low-voltage protection when each cell voltage drops below 3.2V—ensuring longer battery life and safer operation. FET Overheat and Gearbox Lock-up Protection: Built-in fault protection stops the system and issues an alarm when overheating or mechanical jamming is detected. Fully Programmable Firing Modes: Safe/semi-automatic/fully automatic, customizable single-shot, dual-semi-automatic, and 3-9 round burst options. Active Braking System: Ensures precise piston stopping position, resolves the issue of unintended bursts in semi-automatic mode, and reduces stress within the gearbox. Adjustable rate of fire and preload: Fine-tune trigger response and rate of fire via adjustable sector gear stop position and trigger pull delay—ideal for competitive setups. Magnetic sensor system: High-precision gear detection—eliminates the need for white-painted gears and is unaffected by oil or gearbox housing tolerances. Compatible with pressurized magazines: Automatically activates the magazine motor upon connection, performing a 0.5-second pre-feed cycle. Highly durable: Withstands springs, brushless motors, and high-discharge batteries up to M150.

Power off and switch the firing selector to automatic mode. 2. After connecting the battery, press and hold the trigger for 3 seconds until you hear a long "beep," then release. The system will now enter programming mode. (If it does not enter programming mode, switch back to automatic mode.) 3. After entering programming mode, the motor will emit short "beep" sounds. The number of beeps indicates the option index. To select the desired option, pull the trigger within 2 seconds after the beep stops until you hear a long "beep~." The module will then enter the corresponding option. 4. In the selected option, the motor will again emit short "beep" sounds. The number of beeps indicates the setting value. To select the option, pull the trigger within 2 seconds after the beep stops until you hear two longer "beep~ beep~" sounds. The system will then automatically exit programming mode. Installation notes:This unit requires soldering and wiring. Users should possess intermediate to advanced technical skills or consult a professional technician. All connections must be insulated, and reverse polarity must be avoided. Only high-torque motors and appropriate gear ratios (13:1 or 16:1 recommended) may be used. Complete magnetic sensor calibration instructions are included.
