## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0502:1` (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/DFR0502:1.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

**Introduction**

 Gravity IO Expansion Shield with Motor Driver is a new product designed for [Arduino Boards](https://www.dfrobot.com/category-104.html). It combines [IO Expansion Shield](https://www.dfrobot.com/search-Gravity%20IO%20Expansion%20shield.html) and [DC Motor Driver Shield](https://www.dfrobot.com/search-DC%20Motor%20Driver.html), equipped with [Gravity sensor](https://www.dfrobot.com/category-36.html) interface and TB6612FNG dual motor driver. It also has XBee socket, I2C interface and UART port, makes the connections more convenient. With TB6612FNG dual channel motor driver IC, the shield can drive 2x1.2A DC motors at the same time. It supports PWM speed control, each channel can output 1.2A continuous current and the peak current can reach to 3.2A. It is compatible with majority micro DC motors in the market. It is a solid choice for small intelligent robot controls, convenient and cost-effective.
