## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE05023:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE05023:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3/4 with 4 Raspberry Pi Zeros (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.
- Zeros (not included) are powered via Controller Pi GPIO
- Individual Raspberry Pi Zero power controlled via Controller Pi GPIO
- Connector for Controller Serial Console (FTDI Basic).
- Controller Pi can be rebooted without interrupting power to Pi Zeros (network recovers on boot).
 
Kit includes:

- Cluster HAT
- HAT standoffs and screws
- Short USB rope (color may vary)
 
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
- [Support](https://groups.google.com/g/clusterhat?pli=1) for ClusterHAT
 
Console Pinout (From GPIO end of board):

pin 1 = Not Connected
pin 2 = TX
pin 3 = RX
pin 4 = Not Connected
pin 5 = Not Connected
pin 6 = GND
