The NanoHARD is the second programmable MOSFET unit by GATE. Its programmable features are the ON/OFF active braking and an undervoltage protection for 2-4 cell LiPo/Li-Ion batteries. In addition to this, the unit has an updated smart fuse that measures the power flow in real time and thus offers better protection for the battery and the gun. Like other third generation GATE MOSFET unit, NanoHARD is also compatible with microswitches.


  • 3rd generation MOSFET
  • micro-switch compatible (digital signal control)
  • ON/OFF active braking
  • smart fuse
  • undervoltage protection for LiPo AND Li-Ion batteries
  • self-test
  • protective coating
  • programming


  • voltage range for the batteries 7.2V – 14.8V (absolute min and max 3.2V – 17V)
  • compatibility is excellent with highly upgraded airsoft guns (i.a. DSG guns)
  • easy to install – you need only to install the signal wire and change the old connections with conductor surfaces
  • comprehensive protection for the electrical system
  • two LEDs for programming and testing
  • Deans connectors

The package includes:

  • GATE NanoHARD unit
  • extra pair of Deans connectors
  • signal wire (60 cm)
  • double signal wire (60 cm)
  • programming button
  • two jumper wires

MOSFET (Metal Oxide Semiconductor Field Effect Transistor)

The unit reduces power loss due to normal mechanical contact in the trigger switch. When using MOSFET only the signal current flows through the trigger switch and the actual running current goes directly from the battery to the motor. This prevents the burning of the trigger contacts, which is going to happen sooner or later, especially when using powerful batteries – the average lifetime for contact surfaces in an actively used gun is around one year. At the same time, the MOSFET unit enables the maximum power flow in the circuit without unnecessary resistance due to worn trigger contacts. This also gives you a higher rate of fire and a faster trigger response.

3rd generation MOSFET

The use of modern transistors and microprocessors has enabled the manufacture of small and reliable MOSFET units with microswitch compatibility.

Microswitch compatibility (digital signal processing)

With digital signal processing the MOSFET can filter out the vibrations of the microswitch during firing, which might cause excessive sparks and wear in the switch, lower rate of fire as well as heating of the motor, MOSFET, wires and battery, like with traditional MOSFETs. Since the MOSFET filters out the extra signal oscillation, there are no disadvantages of the vibrations created.

Smart fuse

The smart fuse protects the MOSFET unit, the gearbox and the whole gun from electronic problems. The smart fuse is essentially an enhanced electronic fuse. The unit actively monitors the voltage, power and temperature, which ensures the fuse's reliability as well. The fuse protects your gun from both short circuits (SCP - Short Circuit Protection) and overloading (Overload Protection) as well as from overheating (OTP - Over Temperature Protection). Short circuit and overheating protection are important especially with LiPo and Li-Ion batteries, because a short circuited LiPo or Li-Ion battery might cause severe damage also to the gun.

Under Voltage Protection for different battery types (UVP)

Protects LiPo and Li-Ion batteries from excessive drainage. Adjustable for batteries of 7.4V – 14.8V voltages.

ON/OFF active brake

In operation, the motor and the gears accumulate kinetic energy (energy from motion). The magnitude of the energy is mainly determined by the speed of the mechanical parts. The maximum speed is reached approximately after the fourth shot. For this reason, the motor doesn’t stop immediately after releasing the trigger, but continues to rotate for a moment. This is due to the accumulated kinetic energy; the more there is, the longer the motor keeps running “extra”. The active brake is a feature, which stops the running parts with the motor immediately after releasing the trigger.

Benefits of ON/OFF active brake:

  1. No more double shots or double feeding. The gearbox performs only one full cycle with semi-auto. The piston always stays in the front position, which extends the lifespan of your gearbox.
  2. Realism – You get the exact amount of shots with every pull of the trigger as you meant. The advantage can especially be experienced with semi-auto builds.
  3. You can activate or deactivate the active brake according to your needs

NOTE! The active brake is only functional in the advanced installation.


The MOSFET has been equipped with a feature, with which the users themselves can test the condition of the unit. With this feature we can ensure that a problem with the gun is not caused by the MOSFET unit. With the self-test the user can also easily check if the active brake is on or off.

Protective coating

The transparent protective coating protects the MOSFET unit from splashes, debris and minor damages.


GATE Electronics is a Polish company which made its debut on the airsoft market in 2008. Their goal is to provide high-tech electronics for airsoft players worldwide. GATE’s product range consists of MOSFET circuits for all kinds of uses, whether you want a MOSFET which only works as a MOSFET or a MOSFET circuit where almost everything is programmable. The GATE products are easy to install and reliable in use. The products are thoroughly tested and the company listens closely to feedback from end users to uphold the quality of their products.

24-month warranty

GATE MOSFETs have an extended 24-month warranty. It covers manufacturing defects and problems that come up in normal use. The warranty does not cover any fault that is caused by a faulty installation or misuse, like one caused by too high a voltage. You have to use a separate fuse, which protects the MOSFET from short circuits especially with more powerful LiPo batteries, when using NanoASR, -AAB and PicoAAB MOSFETs or SSR series MOSFETs which do not have an electronic fuse. The use of a separate fuse in other MOSFETs is recommended. You will find installation instructions on GATE's website or in Tradetech
