Arduino Ethernet

Preamble

I was looking into single board Arduino Ethernet, where the Ethernet circuitry is on one board with the ATmega, as opposed to being on a separate shield. You may find this link useful, 10 Best Ethernet Shields For Arduino.

The boards

Sparkfun

• Arduino Ethernet w/o PoE, $59.95

eBay

• Arduino Ethernet Development Board A000068 *Brand New*, £10.72 – Same as the SparkFun, w/o POE, but way cheaper

• A000022 Arduino Arduino Ethernet 2, for £39.99 (as above but with sockets already soldered in the holes)

Arduino Ethernet w/o PoE with sockets for POE module

• W5100 Ethernet Module for Arduino With POE/Xbee/SD Slot Iboard Precise, £21.59. This really is a standalone controller, as it has a non-standard form factor, and will not accept shields.

The Modules

• Arduino PoE Module Add On Bolt On, £18.26 + £1.45 (p + p)

• Or cheaper still, 1x X000010 Extension module PoE pin strips In the set prototype board, for £11.59 + £2.98 (p + p)

The Power Injectors

You will also need to inject power into the Ethernet. These seem to vary in voltage, 12V, 15V, 24V, 48V:

• The extremely dangerous looking POE Power Supply 48v 0.5A PoE Injector Adapter US Wall Plug Power over Ethernet, £3.89

Cheap POE injector

• 15V 0.8A POE injector Power Over Ethernet Switch Adapter Injector Power Supply, £3.45 + £0.80 (p + p)

15V 0.8A POE injector

• Genuine Ubiquiti PoE Power Over Ethernet Adapter – Model: GP-D4805-050G, £7.99. 48V 0.5A
