## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SER0011:1` (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/SER0011:1.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 9g micro digital servo is specifically designed for maker DIY projects, robotics competitions, and micro transmission mechanisms. Compared to standard 9g plastic-gear servos on the market, it features solid copper gears and a coreless motor. This completely eliminates the common issue of stripped plastic gears while significantly improving response speed and control precision. Operating at 6V, it delivers a stable torque of up to 1.5kg.cm. Combined with a high-precision digital circuit, the dead band is reduced to ≤3μs, ensuring highly accurate control.

Equipped with a standard JR connector, the servo is perfectly compatible with a wide range of DFRobot Arduino controllers, microcontrollers, and expansion shields. It is fully plug-and-play with no complex wiring required, making it ideal for space-constrained projects that demand precise control.
