Ethernet nodemcu

Question

I have a question that might be a #noob question but I am wondering if there is a board similar to the nodemcu in size that runs arduino code but instead can use ethernet to connect to the network instead of the wifi? I have already seen the connections to use one of the pins and such to connect that way but I am looking to see if there is a board that has the rj45 connection on it already.

• Juraj: closest I found is MKR Zero with MKR ETH shield
• dandavis: while I can't categorically rule it out, I've never seen such a device after hundreds of hours shopping different sites and buying about 15 different models of ESP boards over 2 years...

Answer 1

I don't think you'll find a single off-the-shelf product. The closest I have managed to come to it is a Teensy 3.2 plus a WIZ820io & Micro SD Card Adaptor and a WIZ850io module, all stacked together. Footprint-wise it's around the same as (or smaller than) many ESP8266-based boards - however it's considerably chunkier when all combined:

• nmmooners: Awesome. Thanks all of these are great staring places for me. Thanks so much
• Juraj: "it's considerably chunkier". it is only the RJ-45 connector.

Answer 2

Yes one does exist that I know of. It's called the EtherTen and is made by an Australian company called Freetronics.

EtherTen

It uses the ATMega328P microcontroller that is used on the Arduino Uno. It is 100% Arduino compatible with onboard (RJ45 wired) Ethernet.

It can be purchased from Freetronics.com.au or from Roboshop.com.

Freetronics provides a number of documents and resources on the page linked above.

• Juraj: this is Arduino Ethernet clone. how is this similar to NodeMCU? it is not 32bit and is large.
• sa_leinad: The requirement was that it runs Arduino code. There was no requirement that it had to be 32-bit nor be compatible with NodeMCU (except for size).
