Processor trigger unit ASTER™ V3 SE, Expert firmware

ASTER V3 SE raises the price-performance ratio including new functions programmable via trigger. Now, out-of-the-box, you can set sensitivity from ‘hair’ to full movement. Improved programming via trigger gives you new settings like automatical pre-cocking (LOW, MID, HIGH), trigger sensitivity adjustment, active brake settings with top-class adaptive mode and new SAFE - SEMI - BINARY selector mode. Calibration, DTC codes - all available just via trigger and selector movement. Additionally, you get brushless motor support. ASTER's smart fuse protects your AEG’s battery, motor and the controller, even in case of reverse battery connection. This feature, along with the optical sensors, makes ASTER SE one of the most durable ETU on the market.

ASTER is not just regular ETU/EFCS mosfet. It is the complex system that turns your AEG into future-proof advanced training weapon. You choose how to configure ASTER – simply via trigger or through USB-Link / Blu-Link and our advanced GCS App. You can ask your technician or borrow from friend very popular USB-Link or Blu-Link and use GCS app to update ASTERs firmware, carry out diagnostics or change settings in a very convenient way. If you like it you can get your own Blu-Link and use Smartwatch app, giving you real-time weapon data to reinforce your tactical decisions.

GATE Advanced Weapon Ecosystem thanks to Bluetooth® 5 provides you with GCS app on Android, iOS, watchOS, WEAR OS and compatibility with military-class tactical computer STATUS. It also works with USB-Link and Windows / macOS GCS app.

Optical sensors

ASTER has optical sensors for detecting gear cam, trigger and selector position. With the GCS app, you can easly calibrate, test and adjust these sensors.

Trigger sensitivity adjustment
The trigger sensor offers you even 250 possible sensitivity settings. You do not have to disassemble your AEG. Just use GCS app to adjust the trigger to your preferences and level of skills. You can even activate 2-stage trigger and set two different trigger sensitivities. Pulling the trigger slightly produces SEMI or BURST fire and pulling the trigger further produces BURST, BURST/AUTO or AUTO fire. The 1.5 gen. proximity trigger sensor offers the following sensitivity ranges, depending on trigger construction:

• In total: up to 250 levels
• In the first millimeter of trigger movement: 3 - 15 levels

Selector switching point adjustment
The selector sensor gives you an option for fine calibration of selector switching point. Please note that trigger sensitivity and selector switching point cannot be set while programming via trigger.

Programming via trigger

This programming mode allows you to configure basic functions of your device only with trigger and fire selector. During programming, functions are indicated by corresponding LED colors and vibrations. The following ASTER options can be programmed via trigger:

1. Fire selector mode - blue (unavailable for regional lock)
2. Pre-cocking – bright blue
3. Battery protection – green
4. Active brake – pink
5. Advanced settings – orange

Firmware editions

ASTER is available in 3 firmware editions: BASIC, ADVANCED and EXPERT. The table below contains functional comparison of settings configured via trigger and across ASTER firmware editions.

• BASIC: The best for those who prefer simplicity but require highest quality. Economic version with limited number of functions. If you will decide to have more functions, there is always option to upgrade firmware from BASIC to ADVANCED.
• ADVANCED: The best for those who like complex solutions. Advanced version with wide variety of functions. It enables access to the Statistics and ASTER World Rankings.
• EXPERT: The best for experienced airsofters. Vast diversity of settings and options combined with maximum configuration capabilities allow to prepare for the most demanding mission.

The table below contains a functional comparison of settings configured via trigger and across firmware editions. The comparison applies to ASTER possibilities and TITAN functionality after GBU firmware update. You need to purchase USB-Link or Blu-Link to connect ASTER with GATE Control Station.
