PCB have 8 headers (4 pins, 2.54mm). (With 6 different combinations )

So you connect different I2C modules (with different pin-outs) in just one Node. For example, you can use it to add both si7021 and bmp180 in your project. Sounds cool?

Also USB male and female pass-through, you can create Nodes Chain with several nodes!
