## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2107:1` (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/ADA2107:1.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

Have some USB logic analyzer, multimeter or oscilloscope and bumping up against the frustation of a shared earth ground? The Offspring (known for being electrical engineers) wisely sang "Ya gotta keep'em isolated!" Power and signal isolation improves common-mode voltage, enhances noise rejection, and permits two circuits to operate at different voltage levels.

This handy little low-cost **USB isolator** is exactly what you need to provide protection against harmful noise, ground loops, surges, and spikes. Works with any 1.5Mbps (low speed) or 12Mbps (full speed) USB device. Not for high speed USB devices, often used for video cameras (check your product to make sure its low/full compatible) Based on Analog Device's USB isolators

It is particularly useful when paired with [USB testing instruments](https://www.adafruit.com/categories/85), you need to separate or isolate your eath ground (thru the USB connector to the computer to the power plug) from your circuit for high voltage, accident-protection, or floating ground needs. Best of all, this USB isolator even has its own isolated 5V power supply that can supply 100mA, making it perfect for your [BitScope Micro USB](https://core-electronics.com.au/bitscope-micro-usb.html)! Protect your computer or laptop, use one of these in between your ports.
