A jumper is an electrical connection designed to open or close a circuit between two or more points. Depending on the PCB, jumpers can be added into a design to change the board’s default: Serial UART. I2C Address.

Why are jumpers used in PCB?
In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers. The process of setting a jumper is often called strapping.
What is jumper What is the need?
Jumpers allow the computer to close an electrical circuit, allowing the electricity to flow on a circuit board and perform a function.
Why is jumper wire used?
A jumper wire is an electric wire that connects remote electric circuits used for printed circuit boards. By attaching a jumper wire on the circuit, it can be short-circuited and short-cut (jump) to the electric circuit.
What is a circuit jumper?
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs containing a wire fit down over the pins. The wire connects the pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
What are jumper pins?
The jumper pins are similar to the pins on the I/O plate on a motherboard. You enable particular settings by placing a jumper shunt onto specific pins—creating an electrical circuit between them. The settings these jumpers enable are hard-coded onto a drive’s programmed printed circuit board.
Where is jumper in motherboard?
Open up the system so you can see the motherboard. Locate the CMOS jumper by referring to the motherboard manual and how to clear the CMOS. In general, the CMOS jumper is three pins located near the battery. In general, CMOS jumper has positions 1–2 and 2–3.
What is jumper in mobile repairing?
Jumper wire is used to solder and connect one point of the PCB track with another point. This is generally done when some SMD Electronic Components or IC is faulty and is not easily available in the market. Jumper wire is available in different diameters. It is basically a thin copper wire with laminate.
Where can you use jumper wires?
Attach one red jumper cable clamp to the positive terminal on the dead battery. Attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery. Attach one black jumper cable clamp to the negative terminal of the working (live) car’s battery.
What are the types of jumper wires?
Jumper wires typically come in three versions: male-to-male, male-to-female and female-to-female. The difference between each is in the end point of the wire. Male ends have a pin protruding and can plug into things, while female ends do not and are used to plug things into.
How do you detect a jumper?
Sometimes thieves steal electricity right at the pole. Stand next to the pole and give it a visual inspection. Jumper cables and hanging wires are all signs that something is amiss. Your pole should look like the other poles in your neighborhood.
Is jumper a switch?
Supplied in units of 1 thru 16 poles they provide an alternative to jumpers without the need for ‘parking pins’ on the PCB or exposed bare pins and are available with ON/OFF (JSA4), CHANGEOVER (JSC4), and CENTRE-OFF (JSK9) switch actions.

What is a 2 pin jumper?
These are two pin jumpers (also called shunts) that will create an electrical connection between two pin headers. Commonly used to modify settings on a board or device.
Can you clear CMOS without jumper?
If there is no CLR_CMOS jumpers or [CMOS_SW] button on the motherboard, please follow the steps to clear CMOS: Take out the battery gently and put it aside for about 10 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)
What is BIOS configuration jumper?
A BIOS Jumper, also known as a CMOS jumper, is a small piece of metal with two pins on the end. This metal object has to be moved within the circuit board in order to change certain settings about your computer’s BIOS. Most computers have a BIOS jumper to enable or disable the processor.
Do you need a CMOS jumper?
The cmos pins are used with a jumper to short and reset the bios to defaults. The contents of the motherboard box should have contained a jumper with along with other parts. If not there are ways to short the pins with a paper clip if ever need to reset the bios.
What is GND in mobile phone?
Ground, in the context of electronics, is the reference point for all signals or a common path in an electrical circuit where all of the voltages can be measured from. This is also called the common drain since the voltage measurement along it is zero.
What are the tools and materials needed in Jumpering techniques?
It is important to first track and find the fault or missing track and then do the jumper.
Tools Needed to Jumper
- Jumper wire.
- Precision Screwdriver.
- Soldering iron or Soldering Station.
- Solder wire.
- Blade cutter.
- Multimeter.
- Soldering flux.
- PCB holder.
What is a jumper assembly?
The Concentric Neutral Jumper Assembly is used for bonding purposes on non-jacketed cable. It is usually installed across a portion of cable to be cut, repaired, or spliced. The assembly is left in place until the concentric neutral is spliced.
