Description

A simple ethernet shield for Wemos D1 Mini based on W5500 respecting WizNet directives (https://wizwiki.net/wiki/doku.php/products:w5500:start).

All SMD components are chosen such that JLCPCB can mount them. The only exception is the crystal; replace it with X322525MOB4SI (adapting both schematic and layout) if you want it mounted.

Since JLCPCB can mount either top or bottom only, all the SMD components except W5500 are placed in the bottom layer.

In summary if you take the board as it is, you have to mount manually: •RJ45 connector •W5500 •25Mhz HC-46SMD crystal

P.S. I made two PCBs. The "array" version replace R2, R3, R4 and R5 with a 33Ohm ±5% resistor array (basic part mounted by JLCPCB).
