## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-2002-0180-0002:1` (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/GB-2002-0180-0002:1.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

The goBILDA® Proton Servo is a **standard size servo** offering essential servo function on a budget. There are two versions of the Proton: ‘Torque’ and ‘Speed’. Though their gear ratios differ, they are identical in every other way. The ‘Torque’ version sacrifices speed to optimize its performance in higher torque applications.

While makers of all levels can appreciate the **steel gears** that form the Proton’s core, the nucleus of the design is **beginner-friendly accessibility**! That’s why the Proton’s set of features has been pared-down to the bare essentials:

- **180° of rotation** to turn your ideas into reality
- **75 oz-in of torque** to push your project into innovation
- an **H25T spline**, which you can use to mount all kinds of rotating components found throughout the goBILDA® ecosystem and the wider hobby market

Looking to make your start in robotics, or provide one for someone else? The Proton can be a **fantastic first step** for implementing servo solutions in novice projects without straining your wallet!
