## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA988:1` (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/ADA988:1.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.

## Description

This little dongle will let you connect one of Adafruit's [5V 2Amp](https://core-electronics.com.au/5v-2a-2000ma-switching-power-supply-ul-listed.html) or [5V 10Amp](https://core-electronics.com.au/5v-10a-switching-power-supply.html) adapters to something that expects to connect to USB. The premise is simple - one end has a USB A female jack and the other has a 'standard' 5.5mm OD/2.1mm ID barrel jack with center positive polarity.
 
 It does not have any resistors or other connections inside for the data lines so this won't work for charging an iPhone, iPod or iPad or other device which expects some sort of resistance on the D+ and D- connections. It does, however, work great for Arduinos, BeagleBones, Raspberry Pi's and most other USB-powered gadgets.

## Technical Details

Cable length: 120mm / 4.8"
