T238's flagship ETU for V2 2.0 is one of the best ETU's out there on the market. It's designed to fit into V2 gearboxes and is easily programmed by your smart phone via Bluetooth.

The T238 Adopts a high-speed processor, 8 optical sensors and 2 high power MOSFET chips. It is specially designed for Gel Ball Blasters but can be used for Airsoft with slight modifications and pretty much any other V2 gearboxes.




  • Supported batteries. From 7.4v up to 14.8V battery.
  • Bluetooth. Integrated Bluetooth wireless communication module, use smart phone to program through Bluetooth, can download for Apple iPhone or Android and is a free APP.
  • Magazine Pre-Loading. 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.
  • PRE-COCKING. The default position of the piston is adjustable is semi-auto model. Per-cocking function can be implementing, zero trigger delay.
  • DTU overheat protection. When the DTU is overheated, after the trigger is pulled, the motor will give a beep prompt until it is automatically restarted after cooling.
  • Low battery voltage protection. The default setting is for a 7.4V battery but can be programmed for other voltages. Change the battery when hearing ‘beep beep beep beep’ 4 times low voltage warning sound.
  • Active braking. 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 motors that are paired with the right M spring (M150 motor and a M140/150 spring).
  • Fast speed of response. This module is powered by small current that flows through the MOSFET directly to the motor to provide higher current to increase the rate of fire and speed of response.
  • Block-up protection. When gearbox Block-up occurs, the system stops working and emits an elongated 'beep' sound. Please check the wave box immediately and power off.
  • Multiple shooting modes. The system includes multiple shooting modes those modes can be selected by fire select switch once programmed. These modes consist of Safe, Semi-Auto, Binary, Burst 3/4/5/6 & Full-Auto.
  • Gearbox protection. The active brake prevents the over-spin of gears, this solves the issue that single shot changes to multiple shot under high voltage. Meanwhile, the spring is fully released in semi-auto model and parts in the gearbox are not under strain, increase the life cycle of your gearbox.

Fire Modes:

  • Safe – This mode is completely the same as original safe mode. The trigger can be pulled but nothing happens. The default mode is safe, however this mode can be programmed to semi-auto, double stroke single shot, 3-round burst to 6-round burst.
  • Semi – The default mode is semi, however this mode can be programmed to semi-auto, double stroke single shot, 3-round burst to 6-round burst.
  • Auto – The default mode is full-auto, however this mode can be programmed to full-auto, 3-round burst, 6-round burst, or 9-round burst.
