Describe:
The DTU V2 PRO Light Sensor Version for the V2 gearbox is a drop-in MOSFET module, specifically designed for AIRSOFT replicas, gel ball blasters, such as M4, HK416, SCAR, and other replica/blasters with V2 gearbox. The V2 PRO uses a fully optical sensor design with two trigger sensors that can set the sensitivity and AUG mode of the trigger. It also integrates a short-circuit protection design that can detect the presence of a short circuit in the circuit of the motor or magazine and provide an LED prompt.

Functions:

1. Supports up to 14.8V battery.  

2. Short-circuit protection. When a short circuit occurs in the motor or magazine circuit, the system will stop working and prompt through LED flashing.

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. PRE-COCKING. The piston position in semi-auto mode can be adjusted backward by programming the brake delay time to achieve the PRE-COCKING function and reduce the firing delay.

5. MOSFET 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.

6. Low battery voltage protection, the default setting is 7.4V battery. Change the battery when hearing 4 beeps for low voltage warning sound.

7. Active braking. The active brake prevents the over-spin of gears, this solve the issue that single shot changes to multiple shots under high voltage. Meanwhile, the spring is fully released in a semi-auto model and parts in the gearbox are not under strain, increasing the life cycle of your gearbox.

8. Block-up protection. When gearbox block-up occurs, the system stops working and emits an elongated 'beep' sound. Please check the gearbox immediately by power off.

9. Multiple shooting modes. The system includes multiple shooting modes， those modes can be selected by a selector sensor.
