Morning Gents.. I was wanting to look into an Ethernet connection and trying to see could get one working... I found the Mikroe-971 that would be a "click board" plugin for the E-100 board... It uses the ECN28J60 controller IC and SPI bus comms.. After paging thru the PDF file, I am feeling a bit overwhelmed... Just wondering if anyone else has had any "play time" with this device...  Thanks for any advice...  |

Not surprised, it leaves a lot of work for the host device. Depending on application this is much easier |

Yes, it provides the basic PHY layer but everything above that is left to you. It's a big ask. I looked at using one in a '170 a while back and left it when my code got to almost 30K of unintelligible hieroglyphs... no point as there was no room left for anything decent enough to warrant using it. WiFi is not ideal, but the ESP8266 definitely gets you up and running in a few K, then there is the 5110(?) which does all of the hassles but then leaves you with a couple of basic protocols. I would like something inbetween - a sort of wired 8266 that brought me to the sockets wit a choice of TCP or UDP - I'd be away then. |

How about this: WT32-ETH01 About 8 USD WT32-ETH01 is an embedded serial to Ethernet module based on the ESP32 series WT32-S1 MCU. 32Mbit Flash The module integrates an optimized TCP/IP protocol stack AT Command set Wired Ethernet via a LAN8720A Ethernet Phy (ESP32 supports wired Ethernet via external Phy components) Plus the usual WiFi and Bluetooth Documentation is somewhat "spotty" - needs research... Disclaimer: no own experience at all... |

Documentation bears little resemblance to reality. If I could find a reliable list of AT commands that actually work, I will let you know how good they are. All the write-ups are based on pre-release publicity, not on real hands on use. I keep checking the manufacturers website, hoping for an update... Jim VK7JH MMedit |

Looks like people are using the WT32-ETH01 Board with Tasmota and ESP Easy. So the wired Ethernet seems to work ok But I did not find any practical experience with the ESP32 AT Cmd SW Power over ethernet would also be neat - I use this more and more at home Olimex has a more expensive version with POE support But as the WT32-ETH01 has only 100 Mbit, there are 2 spare pairs for power if needed (with a DIY breakout cable on both sides) |

I've had success with and used the WizNet 107SR modules before. LINK. I don't think I would use them now though, as they are quite expensive compared to the likes of the module that matherp linked to above - I would probably go for that module now. The WizNet module worked OK, and had a nice easy to use GUI application for setup of all it's parameters, good documentation and an active forum for help, they are just a bit pricy these days compared to other modules. Out of interest, matherp, have you used the module you linked to above and if so, how easy(or not!) did you find it to work with? Smoke makes things work. When the smoke gets out, it stops! |

The Lantronix XPort modules are good with plenty of documentation but way too expensive for hobby use. Jim VK7JH MMedit |

Yes, those are another good option. I do remember looking them up when I was playing with the WizNet module, but I too was turned off by the price. Just too costly. Jim - have you used the XPort modules? Smoke makes things work. When the smoke gets out, it stops! |

Yes, that's EXACTLY what those modules do. The module takes care of the complicated network protocol interfacing for you, and you simply talk to them via any standard UART(serial) port and usually TELNET on the network side of things. I had one of the WizNet ones hooked up to a MM2 chip a year or two ago, and as an experiment, I had configured my router(with lots of help from members here) for port-forwarding, and then other members here on the forum could connect to that MM2 chip and use the editor to leave me messages if they got in.  The concept was to prove how easy or not was it to be able to talk to a MM console port via the LAN and WAN, especially from a long way away or even from another country. Smoke makes things work. When the smoke gets out, it stops! |

I bought one to play with a few years ago. I must blow the dust out of it soon. Jim VK7JH MMedit |

Yes, ages ago, but I can't remember any issues. The device has been around for a long time which is good. Lots of info here   Edited 2021-03-28 17:39 by matherp |

Excellent, thanks!  EDIT: So these modules want a dual supply, yes? IE: 3v3 and also 5v? That's what I interpret from the bottom silkscreen. Edited 2021-03-28 20:25 by Grogster Smoke makes things work. When the smoke gets out, it stops! |

No - just connect to the one that works for you |

OK, have ordered a couple to play with. Smoke makes things work. When the smoke gets out, it stops! |

Wow... Much thanks to everyone for all the feedback..!! I didn't know all this was available... |

Perfect - just ordered a couple. I've also just picked a WiModem 232 for a BBC Master project to try out having been intrigued by this video by GlassTTY |
