This product is similar to the Adafruit "T-Cobbler" device
This product only works with Raspberry Pi with 40-pin GPIO. This is a nice quality product with great soldering. I have tested 3 of the batch I am selling and use them every week. You should fit them gently the first time they are used and they fir perfectly after that. I really like it and it's very well made.
