This is a pretty straight-forward HAT for bringing simple cluster computing to the Raspberry Pi A+ and B+ lines. The Cluster HAT from 8086 allows for up to 4 Raspberry Pi Zero or Zero W boards to be connected to a Raspberry Pi A+ or B+ based board (A+/B+/2/3/4). With the Pi Zeros in USB Gadget Mode, the system functions as a small-scale computer cluster. The Zeros plug directly into the HAT via on-board USB 2.0 MicroB connectors.
**Note:** This is just the HAT, USB interface cable, and mounting hardware. All Raspberry Pis must be purchased separately.
