Leviathan - EVO3 is an advanced microprocessor-controlled MOSFET unit programmable via Bluetooth. The EVO3 designation means this unit is compatible with ASG CZ Scorpion EVO 3 airsoft guns. Leviathan brings a wide range of new features to the EVO3 AEG and improves existing functions. With this unit, you can control your gun’s fire modes, rate of fire (ROF), pre-cocking, active braking, protect LiPo/LiFe batteries from over-discharge, and much more. All features are managed via a smartphone app (Android and iOS). The Leviathan unit is installed inside the EVO3 gearbox, replacing the traditional trigger contacts. It comes with pre-installed wiring, including a 30A mini fuse and Deans/T-connectors. No soldering required during installation! Note! The gearbox and trigger shown in the picture are not included with the unit. What features does the Leviathan unit provide? Adjust and add all fire modes in any selector position (SAFE - SEMI - AUTO). Three different burst fire modes. Each burst length adjustable between 2 - 20 shots. Limit the gun’s rate of fire by adding motor pauses between shots. This keeps trigger response extremely fast while reducing full-auto speed electronically. Adjustable active brake strength, which can also be disabled. "Pre-cocking" function for instant semi-auto response without delay. ARL mode: Included anti-reverse latch allows pre-cocking, lower-level active braking, and use of DSG gears. Option to add a delay between shots to simulate the effect of recoil on shooting speed. Delay adjustable between 0.1 - 4 seconds. Automatic fuse detects high current to prevent damage if something goes wrong. Low voltage warning for LiPo or LiFe batteries. Works with 2S - 4S LiPo and 3S - 4S LiFe batteries. User can save multiple configuration profiles. Software displays real battery voltage with a color-coded indicator for charge level. Three separate shot counters: total lifetime shots, user-resettable counter, and one that resets when the battery is disconnected. Error log records all errors during the unit’s lifetime. Leviathan - EVO3 monitors current, voltage, and temperature, protecting components from damage in case of failure. Motor vibrates and beeps to provide feedback to the user. Settings are saved in real time to Leviathan - EVO3 memory, so you won’t lose them if Bluetooth disconnects or the battery is removed during adjustment. Programmable fire modes: Each mode below can be assigned to any selector position (SAFE - SEMI - AUTO). SAFE: Trigger pull does nothing, gun is on safe. SEMI: Fires one shot per trigger pull. SEMI/BurstX: Short pull fires one shot, long pull fires a preset burst. "Double trigger": Fires once on pull and once on release (two shots per full trigger cycle). BurstX: Fires a burst with one trigger pull. BurstX/BurstY: Short pull fires burstX, long pull fires burstX followed by burstY. BurstX/Full: Short pull fires burstX, long pull fires full-auto. Full: Fires full-auto as long as the trigger is held. Specifications: Easy to install in ASG CZ Scorpion EVO 3 AEG, no modification to the gun or circuit required. Compatible with Scorpion EVO 3 - A1, Scorpion EVO 3 - A1 B.E.T., Scorpion EVO 3 - A1 carbine gearbox gen.1, 2018 version, and 2020 version. Works with standard or CNC trigger. ARL mode: Included anti-reverse latch allows pre-cocking, lower-level active braking, and DSG gear use. Sector gear and trigger position monitored by micro switch for perfect semi and burst timing. Includes CNC-machined trigger with adjustable pull length via set screw. Leviathan unit comes with complete wiring for easy installation. Wires are long enough for all EVO3 gearbox setups with battery in the stock. No soldering required. High-quality pre-installed 1.5 mm² (1.5 qmm / AWG16) power wires with durable MPPE insulation and blue 0.34 qmm signal wire (AWG24) Power wire outer diameter: 2.06 mm Signal wire outer diameter: 1.24 mm Wire length from gearbox rear to battery connector: 290 mm Electronic board coated with lacquer for water protection. Pre-cocking function requires anti-reversal latch to prevent gear backspin. Designed to operate with batteries up to 17V. Compatible with 8.4 - 12V NiMH and 7.4 - 14.8V lithium-based batteries. Parts removed from gearbox during installation: cut-off lever and stock electrical components.

Deans/T-connector on wires. Motor wires with standard motor connectors. - ARL mode: Anti-reverse latch, spring, and special screw - Two washers for screws - Foam pad for Leviathan installation - English installation manual Safety Instructions: - Installing the unit inside the gearbox requires knowledge of airsoft gun mechanics. - Read the manual before installation to avoid damage! - Short circuit or incorrect battery connection will immediately damage the unit! Incorrect wiring voids warranty and may cause battery explosion! - Always disconnect the battery when the gun is not in use! Otherwise, the circuit may slowly drain the battery, rendering it unusable. When connected, Leviathan draws a small standby current. - Always ensure the barrel is pointed in a safe direction before connecting the battery! - Do not modify, repair, or expose the Leviathan EVO3 board to liquids or heat.
