Product Description

This is a control board with built-in Ethernet function, like a hybrid of an Arduino Uno R3 and an Ethernet/micro sd shield.
MAC addresses are not unique, you can set MAC address in the code. It comes with a microUSB port instead of the standard Arduino one.
TF card can’t be connected to control board when reading IP address code, otherwise, IP address might be not read Code.
The SD card slot is push release and sturdy. The ethernet port extends beyond the PCB which is nice for panel mounting in a project box.
