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..

Update From kuman 13803KThe sensitivity of DSO Shell oscilloscope has been extended in both directions and is higher and wider than DSO138 oscilloscope. It reaches 5mV/div --- 20V/div while DSO138 is only 10mV/div --- 5V/div.
More Applications Display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers, Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. Without the analog portion the mainboard can be used in many other applications..
Rotary encoder has been added It makes parameter adjustment much quicker and easier..
DSO Shell comes with full enclosure The front panel and top/bottom brackets are flexible for easy user modification..
Detailed InstructionDetailed assembly instructions are provided in combination with troubleshooting guide and schematic..
