## Pricing

- **Price:** $25.90 (inc GST) — $23.55 AUD, exc GST
- **Quantity discounts:** 10+ $22.84 (exc GST) · 50+ $22.36 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA3388:1` (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/ADA3388:1.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

This here is your standard A to micro-B USB cable, for USB 1.1 or 2.0. Perfect for connecting any development board, microcontroller, mobile phone, or other device to your computer or charger.

"Standard?" you might say... nothing gets past the astute eye of an Adafruit customer! Why yes, that *is* an LCD display embedded in the cable!

This is basically like a USB cable mixed with a [Charger Doctor](https://core-electronics.com.au/usb-charger-doctor-in-line-voltage-and-current-meter.html). Plug it into a USB port and it will let you know the voltage on the USB power pins. Once a device is plugged in, it will display the current draw in milliamps. You can use it for up to 2A of current.

You can use this to monitor your project or as a current meter. Adafruit thought they could be neat to use for monitoring current when powering your [Raspberry Pi](https://core-electronics.com.au/#) and other micro B USB devices. The only down side is that once the device starts charging, the display will not show the voltage anymore, just the current draw.

## Technical Details
