## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA324:1` (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/ADA324:1.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

A stepper motor to satisfy all your robotics needs! This 4-wire bipolar stepper has 1.8° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 350mA so that it could be driven easily with an [Adafruit motor shield for Arduino](https://core-electronics.com.au/adafruit-motor-stepper-servo-shield-for-arduino-v2-kit-v2-0.html) (or other motor driver) and a wall adapter or lead-acid battery.
 
 Some nice details include a ready-to-go cable and a machined drive shaft (so you can easily attach stuff). Adafruit drove it with an [Adafruit motor shield for Arduino](https://core-electronics.com.au/adafruit-motor-stepper-servo-shield-for-arduino-v2-kit-v2-0.html) and it hummed along nicely at 50 RPM. To connect to Adafruit's shield, put the wires in this order: Red, Yellow, skip ground, Green, Brown (or Gray)
