1.Description:
 It is a 1660 Hole Breadboard.
 There are many small jacks on the breadboard,which are specially designed and manufactured for the solderless test of electronic circuits.
 Various electronic components can be inserted or unplugged as needed,eliminating the need for welding,saving circuit assembly time,and components can be reused,which is very suitable for the assembly,debugging and training of electronic circuits.

2.Feature:
 1).Easy to install and simple to operate.
 2).Small in size and does not take up space.
 3).It uses ABS plastic panel and tinned phosphor bronze contact piece, which can be used with confidence.
 4).It can be recycled and is environmentally friendly.

4.Operation Method:
 1.) There are several metal jacks connected to the conductive metal strip on the reverse side of the breadboard. They correspond to the small holes on the front.Therefore,when using the breadboard,you need to pay attention.

When inserting the component feet into the small holes,make sure that the component feet are inserted to the end (necessary Tweezers are needed,especially when the integrated block is inserted into the breadboard,it is often easy to cause looseness.

At this time,the two rows of pins of the integrated block can be pressed closer to each other to firmly insert the small hole.

 2.) The test point and the ground terminal in the circuit should be specially led out for measurement,otherwise the probe of the instrument is directly connected to the component foot,which may cause the component to be loosened.
