## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2991:1` (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/ADA2991:1.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

Do you ever find yourself saying, "Gee whiz I wish I could plug in 4 more USB devices to my tablet, or microcontroller with USB host, or a Pi Zero?" I did - literally every single day. But then I found this Micro USB powered hub and stopped having to repeat myself!

This mini USB hub has four USB 2.0 ports each with a max total transmission speed up to 480 MBps. All four ports are powered thru the USB micro-B cable. There's also a single on-off switch that controls the four USB ports. There is a 1.7mm port for an external power supply but its connected directly to the 5V line so if you need to externally power, Adafruit recommend prying open the case and cutting the red 5V line from the USB connection.

This hub is great for expanding your Pi Zero's USB port, or connecting to a tablet or other device with OTG USB, no adapter required!

[We also have a version with USB connector here!](https://core-electronics.com.au/usb-mini-hub-with-power-switch.html)
