GATE ASTER V3 ETU Unit SE Expert Module – Front Wiring

ASTER V3 SE Expert Module by GATE
The ASTER V3 Expert Module from GATE is more than just an ETU processor unit – it’s a gateway to elevating your AEG to the next level. A perfect choice for those who want high-end performance without investing in the more expensive TITAN. It offers excellent value for money in both features and real-world use. For full functionality, we recommend purchasing the USB programming module or Blu-Link to configure your ASTER via smartphone using the GCS – GATE Control Station app (available here). The app also provides usage statistics (e.g., total shots fired) and diagnostics.

Basic Unit Programming
The ASTER ETU can also be manually configured using a selector and trigger. This allows you to adjust the fire mode, pre-cocking, battery protection, and active braking.
