## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=FIT0277:1` (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/FIT0277:1.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 is one of our favourite DFRobot customised high quality DC motor. It is a low noise motor and high torque output motor with hall encoder built-in. The hall encoder gives 663 pulse per rotation which is able to sense 0.54 degree rotation from the shaft. This resolution meets a general PID speed control requirements thus making it a great choice for robotics.

The sturdy metal casing, and gears gives you a change at a competition robot or harsh environments where your robot might get hit from objects or people. This motor is widely used in mobile robot area and some stationary automation devices. The hall encoder is cased on a plastic top easily accesible, and with the included cable you can easily get it connected to your device. Check out our [encoder adapter](https://core-electronics.com.au/encoder-adapter.html) if you want to use it with other controller boards.
