Best RJ45 Ethernet/TCP-IP to TTL module
« on: January 05, 2020, 09:58:34 am »
Hi!
Previous in my working life I have seen Ethernet to TTL modules which did work great but I can't remember the name. Any one having any good tips for a good working board mounted Ethernet/TCP-IP module?

Wiznet is the one used by the official Arduino Ethernet shield.

Cryptocurrency has taught me to love math and at the same time be baffled by it.

I second the suggestion for a Wiznet chip. I do recommend though that for any professional product to put the on the PCB itself and not use a module. I'm not impressed by the layout of the module boards I have seen so far. With some care two layers are more than enough to create a good design using one of the WIznet chips.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Thank you all! I will go with the Wiznet chip. Then I also have the option of just take great inspiration from that layout arduino use. I did find the module I had worked before with: LANTRONIX but they are not low cost.... :(

Better don't. Look at Wiznet's own application notes instead. What is missing on the Arduino shield are TVS diodes and series ferrite beads (10 Ohm@100MHz is a good value) to take care of EMC problems.
