The brand new ASTER II Bluetooth® EXPERT for V2 GB is the younger brother of the well-known TITAN II Bluetooth®. Built-in Bluetooth 5.2 technology gives you direct access to ASTER II Bluetooth® settings, AEG telemetry, and the ability to use our smartwatch app, the tactical computer STATUS, and other future devices of the GATE Ecosystem. Today you can use ASTER II Bluetooth® with your AEG and tomorrow with a single solenoid HPA engine. This makes ASTER II Bluetooth®, right after TITAN II Bluetooth®, the most versatile ETU in the world replacing trigger contacts. ASTER II Bluetooth® raises the price-performance ratio by including an adjustable Quantum Trigger 2 and Bluetooth® 5.2 onboard. You get cutting-edge technologies at a reasonable price. Now, out of the box, you can set sensitivity from ludicrous touch through hair to full movement. Automatic pre-cocking, trigger sensitivity adjustment, Active Brake settings with top-class adaptive mode and the Binary Trigger are all available via Bluetooth® with the GCS app. Extended compatibility with brushless motors – ASTER II Bluetooth® is compatible with popular brushless motors even with a supply voltage of 11.1 V. ASTER's smart fuse protects your AEG’s battery, motor, and the controller. This feature, along with the optical sensors, makes ASTER II Bluetooth® one of the most durable ETUs on the market. ASTER II Bluetooth® is not just a regular ETU/EFCS mosfet. It is a complex system that turns your AEG into future-proof advanced training equipment with built-in Bluetooth®. ASTER II Bluetooth® has a coating in the MIL-V-173C military specification, making it resistant to weather conditions.

ASTER II Bluetooth®: 19 FEATURES with millions of options
BRUSHLESS MOTOR READY
Your ASTER II Bluetooth® is fully compatible with popular brushless motors even 11.1 V batteries.
CYCLE DETECTION
Automatic detection of a full gear cycle for setting BURST and SERIES SAFETY LIMIT.
The ASTER II Bluetooth® sensor detects the cam of the gear instead of the teeth, making it possible to use all types of gears: Infinite Torque-up, DSG, SSG, 19-tooth and standard gears.
ACTIVE BRAKE
Elimination of unnecessary wear & increase of gearbox service life – automatic adjustment of braking power and manual configuration from 0-100% with an accuracy of 1%.
PRE-COCKING & DE-COCKING
PRE-COCKING
Automatic spring compression for real life touch & feel – set the pre-cocking power between 0 and 5. Manually configure the pre-cocking time in MANUAL Mode.
There are two Pre–Cocking Modes:
- AUTO Mode – the spring is automatically compressed after each shot–you choose the level of Pre–Cocking from 0-5
- MANUAL Mode – set the Pre–Cocking values yourself–instead of levels there are time settings, you have to choose the time for yourself by trial and error
Please note: using Pre–Cocking increases wear and tear on the gearbox.
DE-COCKING
Release of the compressed spring in a short and simple trigger and selector sequence. De-cocking extends spring, piston and gear lifecycle. A good practice is to release the spring after every game with enabled pre-cocking.
EQUALIZER
You don't need to fully release the trigger to fire the next shot. This option is really useful when the trigger sensitivity level is very high. Choose between
- OFF – to fire the next shot, you need to release the trigger until it reaches the selected trigger reset point.
- 2LVL – to fire the next shot, just release the trigger until it moves over two adjoining sensors.
- 1LVL – to fire the next shot, just release the trigger until it moves over an adjoining sensor.
SERIES SAFETY LIMIT
Predefined number of BBs fired per series, maximum series length limit – should the trigger jam, it will stop shooting on AUTO after firing the set number of BBs.
VIBRATION NOTIFICATIONS
Vibrations signaling warnings & information.
TRIGGER SENSITIVITY SETTINGS
Trigger sensitivity adjustment without any limitation – what’s more, you can now use Trigger Reset point (hysteresis).
ROF CONTROL
Rate of Fire reduction for stronger battery use, automatic brake and delay settings, setting braking power in percentages, delay between shots in milliseconds or braking power & delay manually; adaptive ROF allows you to set a specific ROF and the system will adjust the settings itself to achieve the set ROF.
SNIPER DELAY
Reload or recoil simulation for a more realistic experience.
SELECTOR MODES incl. BURST MODE
7 options in each selector position including SAFE, SEMI, BURST, BINARY, BURST/AUTO, AUTO & SEMI RAMPING
SAFE – prevents your replica from firing, even if the safety lever is removed
SEMI – fire one shot per one trigger pull
BINARY – one shot on the trigger pull and another shot upon release
BURST – shoot a predetermined number of BBs, which is very useful in MilSims and when using low-caps; there are 2 BURST Modes available:
- Full – a burst is shot in full, even if the trigger is released before the preset number of BBs has been shot
- Interruptible – the burst can be interrupted by releasing the trigger earlier – even if not all the BBs from the burst have been shot the replica stops firing once the trigger has been released
BURST/AUTO – available in Full BURST Mode only; allows for extending a burst by any number of shots – if you hold the trigger after the burst is shot, it switches to AUTO Mode
AUTO – shots are fired as long as the trigger is pulled
SEMI RAMPING – if you pull the trigger very fast, it switches to AUTO Mode
Please note: In the case of Regional Lock, only SEMI Mode is available. Check law restrictions in your country.
MAGAZINE FEATURES
Simulates magazine capacity and magazine reload. Allows you to set the magazine capacity and the time between reloads, allowing you to use a MID-CAP magazine and maintain realism by limiting the capacity, for example, to 30 shots, and setting a pause in shooting for a few seconds, simulating a magazine change.
TELEMETRY
Airsoft data at your fingertips, including: BB Counter, Motor Cycle Counter, Rate of Fire, ROF on SEMI, Trigger Response, and more.
DIAGNOSTICS
Warnings & errors for instant troubleshooting, including detailed descriptions. Errors are communicated once they occur.
VIRTUAL STATUS
Counts the number of rounds left in the magazine, like in computer games.
ASG CALCULATOR
Useful tool for calculations.
SMARTWATCH COMPATIBILITY
Real-time data & remote trigger from your smartwatch with Wear OS or watchOS.
MULTIFUNCTIONAL PORT
I/O functionalities – ability to connect two input/output devices: bolt-catch sensor, magazine sensor, external trigger or other compatible I/O device.
BATTERY PROTECTION & WARNING
- configurable battery protection functionality
- protection against overdischarge
- automatic detection of the number of cells in the battery
- low battery warning
- configurable low battery voltage warning threshold
