Cluster HAT

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.

  • Cluster HAT
  • USB A to Micro B Cable (plugs HAT into host Pi)
  • Mounting hardware
  • 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.

Cluster HAT Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
