Review on SunFounder Ethernet Shield W5100+Mega2560 Board Starter Kit For Arduino by Andres Black

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 replacing the AMS1117 with the 5.0V version, everything worked fine. Otherwise it would be 0 stars. By the way, CS for an SD card on pin 4 interferes with any device that uses the data bus, e.g. B. a TFT display. You need to cut the trace to a contact and redirect the CS to a free contact in your application e.g. B. Pin 53 in Mega.
