**Page:** https://core-electronics.com.au/sparkfun-rj45-magjack-breakout.html ([markdown](https://core-electronics.com.au/sparkfun-rj45-magjack-breakout.html.md))

This is the SparkFun RJ45 MagJack Breakout, a simple board that will provide you with a way to put an ethernet port into your breadboard. The SparkFun RJ45 MagJack Breakout is the same one found in our very own mbed Starter Kit and breaks out each pin from the ethernet jack. This rev of the breakout is equipped with the RJ45 MagJack connector already soldered to the board which mean you no longer need to solder the connector to the board yourself or worrying about buying them separately!

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=BOB-13021:1` (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/BOB-13021:1.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 the SparkFun RJ45 MagJack Breakout, a simple board that will provide you with a way to put an ethernet port into your breadboard. The SparkFun RJ45 MagJack Breakout is the same one found in our very own mbed Starter Kit and breaks out each pin from the ethernet jack. This rev of the breakout is equipped with the RJ45 MagJack connector already soldered to the board which mean you no longer need to solder the connector to the board yourself or worrying about buying them separately!

The on-board RJ45 ethernet jack has a built in transformer (magnetics), status LEDs, and shielding all for better reliability when you use it. As stated before, each pin from the RJ45 MagJack has been broken out, including: P1-P8 (Pins 1-8), Y+ (Yellow LED Positive), Y- (Yellow LED Negative), G+ (Green LED Positive), G- (Green LED Negative), and SH (Shield).
