T238 DTU V2 PRO Optical Sensor Version For V2 Gearbox
T238 DTU V2 PRO Optical Sensor Version For V2 Gearbox
The V2 PRO is a is a programmable MOSFET electronic trigger system based on the T238 platform, engineered specifically for V2 gearboxes. Featuring innovative full optical sensor technology, it integrates intelligent control with comprehensive protection to enhance performance, reliability and versatility.
Utilizes full infrared optical sensors to replace traditional physical micro-switches, eliminating physical contact and mechanical wear.
Features travel learning capability to automatically adapt to your specific trigger and selector plate movement range, ensuring precise operation with various brands and aftermarket parts.
Comprehensive circuit and mechanical protection includes real-time monitoring of motor/magazine short circuits and MOSFET temperature; automatic battery cell detection with adjustable low-voltage protection; automatic shutdown with alarm during gearbox jams to prevent secondary damage.
Compatible gearboxes:
V2: G&G ARP9, Novritsch SSR4/SSR9, S&T M4, JM9, FB1.0-3.0, Kublai, Jingji, Jiqu etc.
DTU
Designed to sync flawlessly with the BL-480 motor. No braking conflicts, just seamless performance—elevate your control.
Tracer Unit
Pair with the airsoft for precision and visibility. Track every shot with unmatched clarity, only from T238.
T238 Digital Trigger Unit V2 PRO
Smart Optical Trigger Unit for AEG/Gel Blaster Enthusiasts
- Travel Learning Capability
- Wear-free
- Contact-free
- AUG Shooting Mode
Full Optical Sensing | Contact-Free, Zero Wear
- How It Works: Employs high-precision infrared optical sensors to detect trigger and selector movement, completely replacing traditional physical micro-switches.
- Key Benefit: No physical contact, fundamentally eliminating mechanical wear. Offers significantly longer lifespan (millions of cycles) and superior reliability compared to traditional trigger boards.
Smart Travel Learning | Perfect Compatibility
- Adaptive Calibration: Unique travel learning function automatically records and adapts to the specific movement range of your trigger and selector plate.
- Wide Compatibility: Ensures precise operation regardless of brand or aftermarket parts used, eliminating misfires or failures due to component tolerances.
Adjustable trigger pull | Two-Stage Control
- AUG shooting mode: In this mode, pulling the trigger halfway results in semi-auto fire, while a full pull activates full-auto.
- Tactical Advantage: Switch between fire modes instantly without touching the selector switch, significantly enhancing response speed and tactical flexibility.
Smart Auto-Loading | Eliminates Dry Fire
- Auto-Detection: Optimized for gel ball magazines with internal motors. Powers the magazine motor briefly upon insertion detection.
- Enhanced Experience: Ensures a loaded first shot every time, effectively preventing dry fire and letting you focus on the game.
Multiple Fire Modes
Quickly switch between settings via trigger programming
- Semi-auto
- Full-auto
- Binary-trigger
- 3 Rounds Burst
- Sniper Delay
5-Safeguard Tech
Short-circuit/ Over-discharge/ Overheat/ Block-up
- Motor Short Circuit Protection
- Gear Block-up Protection
- Battery Over-Discharge Protection
- MOSFET Overheat Protection
- Active Brake Tech
Integrated Ultra-Low Resistance MOSFET
Supports up to 300A inrush current and 85A braking current.
Motor Short Circuit Protection
Automatically cuts off power during short circuits (LED fast flashing).
Gear Block-up Protection
When the sector gear is stuck or the gear detection switch cannot detect gear rotation, the system stops the motor and emits a long 'beep' sound.
Battery Over-Discharge Protection
Emits "Beep! Beep! Beep! Beep!" alarm via motor when battery voltage is low and enters sleep mode.
MOSFET Overheat Protection
When the MOSFETs are overheated, the motor will only emit a short beep after trigger is pulled, then system restarted after cooling.
Pre-cocking
By delaying the braking timing, the piston is stopped at the rear of the gearbox, pre-compressing the spring. On the next trigger pull, the gears only need to rotate a small angle to release the piston and complete the cycle, thereby significantly improving trigger response.
High-Temperature Resistant Teflon Wire - Handles extreme build setups
Features 18AWG diameter for easy bending and shaping, effortlessly fitting into gearbox wire channels.
Universal Fit
Compatible with standard V2 gearboxes (minor mods may be required)
- AEG
- Gel Ball
- Split Gearbox
V2 PRO DTU Offers Front-wire and Rear-wire Versions
The front-wire version features flat connectors for easy T-dean disconnection, enabling wires to pass through narrow spaces.
Choose Your Style
- Rear-wire
- Front-wire
Ideal Use Cases
- Competition Play - Binary trigger for rapid firing
- Gel Blaster Mods - Auto-loading function (magazine motor runs 1s after reload)
- Beginners - Core functions + anti-error protection

Frequently Asked Questions
Frequently Asked Questions
Clarify any uncertainties you might have, ensuring a smooth and hassle-free experience for everyone.
Will the chronograph daybreak work with 43 cal balls?
Only works on airsoft/gelball/foam dart.
This inner diameter is only 14mm, can only be used with calibers smaller than 14mm.
Why are triggers and selectors not effective in all cases?
The causes are as follows:
1. Battery failure
2. Poor contact of the battery plug
3. It is recommended to change the battery to troubleshoot
4. If you still can't solve the problem, please contact: support@t238.net
Can T238 Storm works with red bbs?
It's not allowed to be used! Green only!
Have a question about the Daybreak tracer/chronograph. Is there a way to keep the screen off when in use? For instance, does the screen turn on when I fire?
You can set auto display off to 5s. and when you fire, the screen will auto-turn back on.
How do I reset the FCU to factory settings?
Click the reset button in FCU settings.
Is the IMPULSE rated for 30c continuous discharge and 60c sudden discharge?
