The I2C connector is 4 pins. There are 4 connectors on each board. 2 on both sides of the USB connector and 2 on the edges right next to the edge with the USB connector. The 3 Pin connector is for the fan. TerraHash boards will each come with a I2C jumper cable to daisy chain the board with another one.
That is awesome. So we are going to have a fan, heatsink, and I2C connectors packaged alongside our K16s? How about standoffs for stacking K16s?
yes and send someone to my house to set them up too!!
