- **Price:** $29.90 (inc GST) — $27.18 AUD, exc GST
- **Quantity discounts:** 10+ $26.36 (exc GST) · 50+ $25.82 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 6 today, and up to 500 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1901:1` (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/ADA1901:1.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

If you have a modern smart phone you may have noticed that it comes with built in wireless charging capability called 'Qi charging.' Qi is a trademark name for a thin and smart inductive charging system. Many large gadget companies have standardized on Qi, which means it's easy to find a charging dish and Adafruit thought it might be cool if your Arduino project can recharge itself wirelessly. Thus, Adafruit now have a Qi charging receiver module as seen here here.

This is just the inductive charging Qi receiver. It will work with any Qi charger base transmitter that will work well with any standard inductive charger base. Simply solder two wires to the V+ and Gnd pins on the Qi module and place the item you want charged onto a charging base. The receiver chip manages the coil so that you'll always get 5V and 500mA. If the coil is too far it will simply not activate at all. In Adafruit's demo, Adafruit used a classic cell phone charger plate.

[The driver chip is an integrated receiver called the BQ51013B from TI](https://core-electronics.com.au/attachments/localcontent/bq51013b_33604c7ec2e.pdf). Since its a Qi charger it can only be used with Qi transmitters! [If you want a simpler inductive charger, check out Adafruit's 5V charger set](https://core-electronics.com.au/inductive-charging-set-5v-at-500ma-max.html) - it isn't Qi compatible but used together it works quite well!

To demo it, Adafruit wired the module to a [MiniLipo charger](https://core-electronics.com.au/adafruit-mini-lipo-w-mini-b-usb-jack-usb-liion-lipoly-charger-v1.html) and [a LiPo battery](https://core-electronics.com.au/lithium-ion-polymer-battery-3-7v-1200mah.html), as shown in the photos. Now Adafruit have a wirelessly-rechargeable battery! Note that you don't get the battery or lipo charger in your order, that's just how Adafruit are showing it off. You can even upgrade any device that takes classic USB 5V and up to 500mA. The coil comes on a metallic sticker which is used to shield the device from the coil. Make sure the coil is facing out towards the charger when you install it into your project, or it wont work at all!
