The Cluster HAT v2.6 interfaces a Raspberry Pi 4 (or older A+/B+/2/3/4) with 4x Raspberry Pi Zero W boards (not compatible with the Raspberry Pi Zero 2 W due to the additional power the Zero 2 requires). **Raspberry Pi and Pi Zero boards not included** Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small-scale clusters. * USB Gadget Mode: Ethernet and Serial Console * Onboard 4-port USB 2.0 hub * Raspberry Pi Zeros are powered via Controller Pi GPIO * Individual Raspberry Pi Zero power controlled via Controller Pi GPIO * Connector for USB Serial Adaptor (FTDI 3.3v) * Controller Pi can be rebooted without interrupting power to Raspberry Pi Zeros (network recovers on boot) * 2 pin (0.1" pitch) header for a 5V fan (200mA max, controlled by GPIO BCM18). Also check out our Cluster HAT Case! Resources As with most things there are many ways to configure the ClusterHAT. If you know what you're doing with Linux kernel Gadget mode and networking you can probably skip most of these. * Assembly - Connecting the ClusterHAT (plugging/unplugging the Pi Zeros). * Software - Installing our Customised Raspbian for the Controller and Zeros. * Control - Controlling power to the Pi Zeros Package Contents * 1x Cluster HAT v2.6 * 4x 12mm M2.5 standoff * 8x 6mm M2.5 screw * 4x stick on feet * USB Cable Raspberry Pi and Pi Zero boards not included https://elecena.pl/product/22716100/cluster-hat-v2-6 2023-03-07 https://elecena.pl/product/22716100/cluster-hat-v2-6 2023-12-27 https://elecena.pl/product/22716100/cluster-hat-v2-6 2024-09-19 https://elecena.pl/product/22716100/cluster-hat-v2-6 2024-11-29 https://elecena.pl/product/22716100/cluster-hat-v2-6 2024-11-30 https://elecena.pl/product/22716100/cluster-hat-v2-6 2025-11-28 https://elecena.pl/product/22716100/cluster-hat-v2-6 2025-11-29
