Wayne's Embedded 10Mbps Ethernet Module

Add Ethernet to your next project now

Check out the prototype Ethernet server page

This Ethernet module uses a cheap and easy to interface 10Mbps RTL8019AS Ethernet controller from Realtek. The module requires just 5Vdc and an 8-bit data, 5-bit address, read, write strobes and a reset signal. 4 LED's show the status of the module. From left we have a power LED, transmit LED, receive LED and link LED. The link LED can be configure to be a collision LED in software.

Currently in development is a ATMega128 processor board that will fit under this Ethernet module. This board has two serial ports and I/O pins that can be used to control a range of stuff. Quick interfacing to GPS and other serial devices for realtime access across your network.

These will be double sided, solder masked and silk-screened
