Advanced Technology Driven by a powerful PIC18LF2321 microprocessor for both speed and versatility. Uses the latest in ultra-small SMD components and PCB technology to minimize dimensions. On-board supercap and voltage booster allows normal operation under voltage droops as low as 2.5V. Short-circuit, under-voltage, over-voltage(ESD), and over-current safeguards. Advanced thermal management allows passive cooling even under sustained semi-fire. Micro-amp sleep current allows batteries to remain connected for several years.

MOSFET Trigger Eliminates damaging electrical arcing of the trigger switch contacts. Lower resistance compared to mechanical switching, increasing motor current. Rated for 200A continuous operation and 800A startup inrush current.

Active Braking Eliminates the motor spin-down time, preventing piston over-travel on semi-fire. Allows semi-fire to properly reset the piston in any AEG setup, preventing component stress. Specially designed to dissipate the braking heat in the wires instead of the controller.

Cycle Completion Gearbox always completes a shot cycle regardless of when the trigger is released. Allows ANY firing mode to properly reset the piston regardless of AEG setup. With the piston always reset, every shot gets the smoothest possible motor startup. Allows the anti-reversal latch to be removed (although not recommended).

Burst Fire Mode Available burst trigger groups: Safe - Semi - Burst Safe - Burst - Auto Sensor detection of each cycle provides reliable and foolproof burst fire operation (no timing involved).

Semi-only w/ Precocking Safe - Semi - Semi (precocked) configuration converts any AEG into a semi-only rifle. "Precocked" option stops the piston when ~75% compressed so the next shot is near-instantaneous. Offers realism for DMR-style AEGs and compliance to semi-only laws in certain countries.

Adaptive RoF Control Adaptive RoF reduction to EXACTLY 10, 15, or 20 rnd/sec on any setup. Every cycle runs at full speed and pauses between each shot to reduce RoF. Very realistic sound and feel when enabled on very high-speed AEGs.

LiPo / LiFePO4 Monitoring Monitors LiPo and LiFePO4 batteries to cutoff power before overdischarge occurs. Calculates the cell voltages via the main line, reducing wire clutter.

Serial Comm Port Communication port for transmitting signals between custom add-on circuits (ie: ammo display). Ouput signals include "shot fired", "trigger pressed", trigger released", etc. Input override signal allows add-on circuits to take control of the FET.
