# DFRobot Leonardo with Xbee socket

**Type:** Product page · **SKU:** DFR0221 · **Brand:** [DFRobot](https://core-electronics.com.au/brands/dfrobot-australia)
**Page:** https://core-electronics.com.au/dfrobot-leonardo-with-xbee-socket.html ([markdown](https://core-electronics.com.au/dfrobot-leonardo-with-xbee-socket.html.md))

DFRobot Leonardo with Xbee socket is an Arduino Leonardo variant board based on the ATmega32u4 chip. Because the ATmega32u4 handles USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!

## Pricing

- **Price:** $26.55 (inc GST) — $24.14 AUD, exc GST
- **Quantity discounts:** 6+ $22.93 (exc GST) · 12+ $21.96 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 1 today, and up to 100 more in 8–12 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0221:1` (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/DFR0221:1.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

DFRobot Leonardo with Xbee socket is an Arduino Leonardo variant board based on the ATmega32u4 chip. Because the ATmega32u4 handles USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!

Based on the Arduino official Leonardo processor, this board features an Xbee socket making it possible for you to extend the functionality of your Leonardo with WiFi, Bluetooth and RF directly. Pins D14, D15 and D16 have been broken out with power and ground pins to maximize the use of your ATmega32u4 microcontroller allowing for digital sensors and modules to be used directly with your DFRobot Leonardo.

Note: This board is only supported in the latest Arduino IDE 1.0.1 or later version so you will also need to update the IDE.
