SunFounder Ethernet Shield W5100+Mega2560 Board Starter Kit For Arduino Review

I haven't used it much but I was able to connect it to my OSEPP Uno R3 plus without any problems. I uploaded some quick sketches and was able to access them through a separate web browser. Physical and network connections work as expected. Light!

A very nice price for a standard Ethernet board based on the W5100 chipset. It started with the standard libraries on the first try. Within minutes I had an Arduino web server up and running temperature and humidity statistics on the internet. Don't use the big little board.

The obvious flaw with SunFounder is the NULL documentation. Do you think they even put the circuit on their website? No, they rather advertise their IoT cloud. And I bought two of these at once and a few months later another Mega 2560 from another source. In all devices, the 5.0V register was filled with a 3.3V chip! Luckily, Revain refunded my money with no fuss. For another dollar you can get an Elegoo device with the right paperwork and pins on the straps! even after a few weeks. After…

I had this piece of rock because I couldn't get it to work properly. No connection to Arduino. The pins were too long to fit, the solder under the board touched the USB connector on the Arduino board. Until I buy some Arduino connectors to form the second layer, I manage to work through the example sketches one at a time and repeat the tests. Before this HACK board, it wasn't very reliable. I'm still testing reliability as sometimes the board worked, sometimes not. Today is the first day I've…

When I bought this I needed an Atmega microprocessor for a class project. I looked at real Arduinos and half the posts complained about "fake", "cloned", or "Chinese" fake Arduinos. While I have no problem supporting an open source program by buying the original at a higher price, I have a serious problem paying that price for a product not made by them. I would rather buy a copy from a reputable company who will sell it as a copy for the price of the copy and then donate the difference to…
