Why so many airsoft players choose smart ETU?

With the continuous development of the Airsoft industry, more and more manufacturers will install ETU when producing new Airsoft replicas that players can be experience more functions than traditional mechanical triggers. ETU is simple in function and economical thus it becomes one of the favorite addon by manufacturers.  However Airsoft players are not satisfied with this, more and more players wants to upgrade their replicas by more functions and better performance which can bring them more experience and fun. Since then, they set their sights on the Smart ETU.

In the beginning, the main purpose for players and manufacturers to use ETU was to prevent the trigger contacts from wearing out.  Standard AEG (without ETU) used microswitches as switches for the high-current energization of battery-operated motors.  Contact wearing is caused by this high current, which creates a voltage spark between the trigger contacts when the Airsoft starts or stops firing.  Voltage sparks can damage the contacts with the continuous usage.

At present, 11.1V batteries are equipped by the manufacturers, you need to repair your favorite gun sooner or later without using ETU in Airsoft. This means it affects the cost, satisfaction and wastes a lot of precious time.
Reliable and non-wearing trigger contacts are just the beginning of ETU development, there are two major types of Airsoft ETU in the market which are normal ETU and smart ETU.  A normal ETU is only a basic unit designed to improve Airsoft's safety and performance while the smart ETU is likely a motherboard with all integrated functions, this is a single unit with advanced features that offer you an edge in the game, such as faster trigger response sensitivity, higher rate of fire and even programmable bursts model.

Smart ETU Advantages(t238 V2 2.0 as an example)

1.Supports up to 14.8V battery.

2.Bluetooth module.Integrated bluetooth wireless communication module, use smart phone to program through bluetooth, can download Android free APP.
3.Multiple shooting mode. The system includes multiple shooting mode, these modes can be selected by fire select switch
4.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.
5.PRE-COCKING.The default postition of the piston is adjustable is semi-auto model.Per-cocking function can be implementing,zero trigger delay.
6.ETU 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.
7.Low battery voltage protection:the default setting is 7.4V battery.Change the battery when hearing‘beep,beep,beep,beep’4 times low voltage warning sound.

8.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 motor.
9.Fast speed of respond.This module is powered by small current,the current flow through the MOSFET directly to the motor,provide higher current to increase the rate of fire and speed of respond.
10.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.
11.Multiple shooting modes.The system includes multiple shooting modes,those modes can be selected by fire select switch.
12.Gearbox protection.The active brake prevents the over-spin of gears,this solve 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.
