ZYAMY 30pcs 2.54mm 6Pin 8Pin 10Pin Female Socket Pin Header Strip Kit Single Row Straight 11mm Long Needle Stackable Header Strip Connector Black PC104

These things allow you to add headers to a board with the proper pin spacing and have a male header on one side and a female header on the other. Adds a bid more flexibility to your proto board.

These connectors seem particularly useful for connecting to 433MHZ transmitter/receiver modules, LM386 audio amplifier modules and for power transistor and MOSFET devices.

I received: 10 x 10pin connectors 12 x 8pin connectors 10 x 6pin connectors So 32 total pieces, in an easy to open, biodegradable cardboard box. The other reviewer clearly did not order this, and wrote a hypothetical, misleading review.

I got in a bind and had to get something for an order. I knew from the description that for some reason, they only have 10 of each 10pin, 8pin, and 6pin headers. Arduino shields need 2 8pin headers. So I had to order 2 kits and just waste all the 6 and 10 pin connectors in the other box. These are the standard stamped metal fork connectors embedded in the plastic header. They are cheap, flimsy, and thin, so the can often not make a good connection. But worth noting, this is what often comes on shields anyway. They are also 11mm long, the regular shield pins are 14mm with tough, square pins, but are hard to find and twice as much. These will do for personal projects where you aren't going to be plugging and unplugging them a lot.

These inexpensive headers where exactly what I needed to make some Arduino Uno shields for various projects.

Will do the intended job perfectly.

This product has a nice selection of pins to use , I will buy from this company again.

I used mine for Arduino Protoboard projects. was easy to line up and solder. the pins a little thin and fragile, di not break but the get bent easily, making it hard to line up.
