I’m currently shopping for a new ethernet module/shield, since the ENC28j60 requires too much storage (Blynk example needs around 80% of flash vs. around 50% for the W5100 or W5500).
Does is matter for Blynk whether I choose a W5100/W5500 module or a real shield?
I heard that some Asian manufacturers use wrong resistors for some ethernet modules or shields, which leads to issues with certain routers/modems. Does this apply to both W5100 and W5500 shields? Is there anything I should look out for to avoid this?
Which is the more reliable board? The W5100/W5200/W5500? Does Blynk even support the W5200?
Arduono Ethernet shields are generally quite flakey, and often don’t work with some routers/switches. I tried a variety of different ones, and found the whole process far too frustrating. Eventually I woke-up to ESP8266/NodeMCU boards and ditched the Arduino all together.
I’ve not yet found a situation where I needed to use an Arduino for anything other than getting other people’s code working successfully before tweaking it to work on an ESP.
