Best Single double Sided Pcb

American Bass Amp D Class 1 Ohm Stable 4000 Watts Max

Power up to 10 PC fans from a Single 4-Pin Motherboard PWM Fan Header.Note: Max current limit is 3A in total, check the spec of fan first..
In the hub interfaces, the White interface of FAN1 is the CPU fan dedicated interface (with speed detection function). Since the mainboard can only receive one rotation speed signal, the remaining nine conventional fan interfaces have the PWM function, but no speed signal..
There is EVA double-sided adhesive in the package, which can be easily affixed to a flat place. Also a fixing screw hole in the middle of the PCB to facilitate fixing to a part of the chassis..
Direct computer power supply to reduce the mainboard loading pressure, and PWM temperature control line separated from mainboard to achieve both of power supply and temperature control..
If 3-pin fans are connected to this fan hub, this fan hub CANNOT give them extra PWM function. They will run at FULL SPEED..

-The ultrasonic generator can monitor the power system frequency ultrasound power..
-According to different requirements of users, real-time adjustment of various parameters: The power, amplitude, and running time..

Using 1.6mm thick PCB double sided board, sturdy and durable, come with long service life.
The interior is composed of double balanced microwave diodes, come with high reliability.
35dB high isolation between local oscillator and RF input, which is stable and reliable.
The product have large heat dissipation area, possess stable operation and long running time.
The conversion loss is only 8.0dB, and the noise figure is as low as 8.0dB (SSB). This is a passive device and does not require power supply.

Package Included: CNC Case + Rubber Feet + Screws.
New GK61x GK61xs GK64x GK64xs plate and PCB can install in directly..
Old GK61 GK64 plate can't use since the size is bigger than normal 60 case.You can just replace a GH60 size customized plate is ok.The plate need to be compatible with GK61 PCB..
How to judge old and new edition: Old GK61 GK64 PCB is white and only support single 6.25u space New GK61x GK61xs GK64x GK64xs PCB is black and can support split space and single space at the same time..
There is no switches in the kit,you can order Cherry Gateron Kailh SMD Box switches etc yourself.Just put in switches in PCB is ok,no need soldering again.3 pin 5 pin both are ok.If little keys not working,check the switch pin whether it's bent at first.Especially Kailh switches.
