GATE ASTER SX ETU Module

The ASTER SX is designed specifically for Version 2 gearboxes, which are standard in most M4/AR-15 style AEGs. Because it is a drop-in module, it replaces your existing trigger contacts and cut-off lever, but you should ensure your gearbox shell is compatible with standard V2 ETU installations before purchasing.

Yes, the ASTER SX is fully compatible with high-torque brushless motors. Its advanced electronics are built to handle the unique electrical demands of brushless systems, providing smoother operation and better response times than traditional brushed setups.

You have two options for customization: you can program basic settings directly through the trigger pull sequence, or you can use the dedicated mobile app for a more visual, granular experience. The app also allows you to perform firmware updates and access real-time diagnostics.

The ASTER SX operates within a voltage range of 3.75V to 12.9V. This means it safely supports standard 7.4V LiPo batteries all the way up to 11.1V LiPo packs, which are recommended for optimal performance and trigger response.

Active braking stops the motor instantly after each shot, preventing the gears from over-spinning. This is particularly useful for preventing double-feeding in semi-auto mode and ensures your piston consistently stops in the correct position for your next shot.

Absolutely. The ASTER SX is engineered to handle robust spring setups up to M200. Its durable PCB construction is designed to withstand the stress of high-performance builds without failing under the tension of stronger springs.
