JT-LEV-V3
Leviathan V3 Optical ETU unit by JeffTron with front wiring (handguard / above gearbox). Designed for gearbox V3 (AK series, G36, CZ805 Bren, and others). Bluetooth programming via JeffTron app (iOS / Android). Hair trigger mode. Ready for Brushless motors. RFTS system – resistance similar to a real firearm.
This external control unit is designed for connection to Leviathan optical control units. It allows users to easily activate selected unit functions directly from the handguard. The dual switch combines a round ON/OFF toggle switch and a pressure pad, wired in parallel to offer faster control of features like hop-up chamber lighting, 3-round burst mode, or virtual magazine reload. To function properly, the switch must be connected to the INPUT port (SIG and GND) of a compatible Leviathan unit and the feature must be assigned through the JeffTron mobile app under “External Input”.
Installation requires advanced soldering skills. Wires must not touch other components on the board. Improper installation may cause irreversible damage to the Leviathan unit and void the warranty.
