## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DRI0025:1` (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/DRI0025:1.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

 The SyRen motor driver is one of the most versatile, efficient, and easy-to-use motor drivers on the market. It is suitable for medium-powered robots - up to 50lbs in combat or 180lbs for general-purpose robotics. Out of the box, the SyRen 25 can supply a single DC brushed motor with up to 25A continuously. Peak currents of 45A are achievable for a few seconds. Overcurrent and thermal protection mean you'll never have to worry about killing the driver with accidental stalls or by hooking up too big a motor. With just one SyRen driver you can control a motor with analog voltage, radio control, serial, and packetized serial. You can build many different robots of increasing complexity for years to come with a SyRen. Owning two SyRens allows you to build differential drive (tank style) robots because they can work in tandem with built-in mixing. The operating mode is set with the onboard DIP switches so there are no jumpers to lose. The SyRen features screw terminal connectors - making it possible for you to build a robot without even soldering. SyRen is the first synchronous regenerative motor driver in its class. The regenerative topology means that your batteries get recharged whenever you command your robot to slow down or reverse. SyRen also allows you to make very fast stops and reverses - giving your robot a quick and nimble edge. SyRen has a built-in 5V BEC that can provide power to a microcontroller or R/C receiver. The lithium cutoff mode allows SyRen to operate safely with lithium-ion and lithium polymer battery packs - the highest energy density batteries available.  SyRen's transistors are switched at ultrasonic speeds (32kHz), meaning no one will be able to hear your robot ninja army approaching. Use of these motor drivers with cheap AC adapters is not recommended. Use a battery or at least put a battery in parallel with a DC supply to ensure a consistent power input to your system. #### Applications
