Hardware List
The following contains a list of required (and optional) hardware components for your cluster.
| Component | Quantity | Priority |
|---|---|---|
| Raspberry Pi 4 Model B (2GB) | 5 | Required |
| 16 or 32 GB microSD Card | 5 | Required |
| USB Wall Charger 2.4A Multi-port* | 1 | Required |
| USB Type C Cables | 5 | Required |
| 5-Port Network Switch | 1 | Required |
| Ethernet cables | 5 | Required |
| Keyboard | 1 | Required |
| Mouse | 1 | Required |
| Raspberry Pi 4 Model B Heatsinks | 5 | Optional |
| Raspberry Pi Cluster Case | 1 | Optional |
| 7-inch Computer Monitor | 1 | Optional |
| Micro HDMI to Mini HDMI Cable | 1 | Optional |
* The full specification list for Raspberry Pi 4 Model B specifically establish that the board requires a 5V DC via USB-C connector with a minimum of 3A. Yet it also specifies that a good quality 2.5A power supply would do the job if all USB peripherals are kept under 500mA load consumption in total.
I have not had any issues with this, but wanted to share in case your Raspberry Pi board does not power up properly, you may need to verify this.
