T238 1.9 Digital Trigger with Wires Set for AIRSOFT Gel Ball Gearbox V2 with Programmable Overheat Protection Active Braking


New Upgrade  Version 1.9 V2:


Gear sensor detection stability

Alleviate MOSFET chip heat

Enhance anti-interference

Suppress interference from motors and static electricity




T238 digital trigger unit is a programmable MOSFET which is specially designed for AIRSOFT and gel ball version Gearbox V2 . With high speed processor and 2 high power MOSFET chips, this system has many functions, such asbinary trigger, auto-loading function for gel ball magazine, over heat protection and so on. Besides, it also has the functions of  gearbox block-up protection. It can effectively improve the stability, shooting speed and response speed of gearbox. The module uses a maximum of 11.1V batteries. Soldering and wiring are required.

Main parameters:
Size: 45*30*14mm
Operating voltage: 7.4-11.1V
Active break tech
Uses optical sensor for gear detection
Binary trigger shooting mode
Overheat protection
Maximum Inrush current is 300A, Maximum Brake current is 100A
Compatible with various Standard Gearbox V2


1. Binary trigger. Put the selector in semi-auto position, pull and hold the trigger for 3 seconds will change the semi-auto function into binary trigger shooting mode.
2. Block-up protection. When gearboxBlock-up occurs, the system stops working and emits an elongated 'beep' sound. Please check the wave box immediately by power off.
3. Auto-loading function is designed for gel ball blaster magazines with motor inside, when changing the magazine, the magazine motor will run automatically for 0.5 second.
4. This module is able to increase rate of fire, the stability of single-shot and make batteries have higher durability.
5. The energy that support the active brake function comes from the inertia of motor, stop the piston without delay. The effect of active brake is significant  on high torque motor
6. The active function prevents the over-spin of gears, this solve the issue that the single shot becomes multiple shot under high voltage.  Meanwhile, the spring is fully released in semi-auto mode and parts in gearbox are not under strain, increase the life cycle of gearbox and parts.
7. When the DTU is overheated, after the trigger is pulled, the motor will give a beep prompt until it is automatically restarted after cooling.
