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. **Includes:** * Cluster HAT * USB A to Micro B Cable (plugs HAT into host Pi) * Mounting hardware **Features:** * USB Gadget Mode Functionality: Ethernet and Serial Console. * Onboard 4 port USB 2.0 hub. * Raspberry Pi Zeros are powered via Controller Pi GPIO (USB optional). * Individual Raspberry Pi Zero power controlled via Controller Pi GPIO (I2C). * Connector for Controller Serial Console (FTDI Basic). * Controller Pi can be rebooted without interrupting power to Pi Zeros, network recovers on boot. **Documents:** * [Getting Started Guide](https://clusterhat.com/setup-overview) * [FAQs](https://clusterhat.com/faq) * [How Tos](https://8086.support/category/23/cluster-hat.html)
