GATE ASTER II Bluetooth® Airsoft MOSFET Module w/ Quantum Trigger (V2 & HPA Expert Rear Wired)

The GATE ASTER II Bluetooth is a next-generation Electronic Trigger Unit (ETU) designed for serious airsoft players who demand precision, programmability, and real-time system control. Compatible with both AEG and HPA setups, this V2 Expert rear-wired module transforms your rifle into a fully tunable, data-driven platform using Bluetooth 5.2 and the GCS ecosystem.

Whether you're building a high-speed DSG, a torque-focused DMR, or a competition-ready HPA system, ASTER II Bluetooth delivers unmatched control over trigger response, firing modes, and internal performance.

Advanced Bluetooth 5.2 Airsoft Control System

With built-in Bluetooth connectivity, ASTER II removes the need for external programming devices. Everything is controlled directly through the GATE Control Station (GCS App).

You can manage your replica in real time using your phone, tablet, or even smartwatch.

Key connectivity advantages:

• Bluetooth 5.2 low-latency communication

• Firmware updates directly via GCS app

• Smartwatch integration (Wear OS & watchOS)

• Real-time telemetry (BB counter, voltage, diagnostics)

• Wireless configuration without USB-Link or dongles

Precision Trigger Control with Quantum Trigger 2

At the core of the system is the adjustable Quantum Trigger 2, designed for extreme responsiveness and customization.

Trigger performance features:

• Up to 35 sensitivity levels in the first millimeter of movement

• 680 total trigger sensitivity steps across full pull range

• Configurable trigger reset (hysteresis)

• Hair-trigger capability for ultra-fast response

• Adjustable over-travel via screw tuning

This level of precision allows players to tune their trigger feel from competitive “hair touch” setups to full-stroke realism.

Smart Firing Modes & Advanced Programming

ASTER II Bluetooth is not just a MOSFET—it is a fully programmable fire control system.

Advanced fire control options:

• Safe / Semi / Full-Auto / Burst modes

• Binary trigger support

• Ramping fire modes

• 343 selector combinations

• Adjustable active braking (0–100% or adaptive mode)

• Automatic pre-cocking (0%, 20%, 40%, 60%, 80%, 100%)

Pre-cocking delivers near-instant trigger response, simulating real firearm behavior while improving reaction time in CQB environments.

AEG + HPA Compatibility & Ecosystem Integration

ASTER II Bluetooth is designed for maximum platform flexibility. It works seamlessly with:

• Standard AEG gearboxes (V2 & V3 compatible setups)

• Single solenoid HPA engines

• High-torque, DSG, SSG, and brushless motor builds

• 11.1V LiPo and low-voltage systems

Integrated into the broader GATE Ecosystem, it connects with future tactical devices and software expansions.

Built for Reliability and Efficiency

Engineered for endurance and battlefield conditions, ASTER II includes:

• Ultra-low power consumption (deep sleep mode ~140µA)

• Built-in voltage boost converter for weak batteries

• Smart fuse protection for motor, battery, and electronics

• Multi-layer PCB with EMC shielding for interference resistance

• MIL-spec protective coating (MIL-V-173C standard)

These protections ensure long-term durability even in high-stress builds.

Full GCS App Tactical Control

The GCS app turns your airsoft gun into a programmable tactical system.

App capabilities:

• Live battery and voltage monitoring

• BB counter tracking

• Trigger tuning and fire mode configuration

• Firmware updates and diagnostics

• Game-time adjustments via smartphone

• Performance logs and system analytics

Key Takeaways

• Full Bluetooth 5.2 programmable MOSFET/ETU system
