Questions tagged [ethernet-shield]

The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top. The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network.

Can I reduce UIPEthernet library size (perhaps by ditching TCP)?

I am using the excellent UIPEthernet library to get an Arduino Nano to drive an ENC28J60 Ethernet Shield for a UDP-based application. But I think the poor library has to do a lot of work to make up for the limitations of the ENC28J60, and that makes…
