"EMail" Project

Looking back at this project, it really is a nice beginning to what could be a range of different PICmicro Internet applications. The project here is really just the beginning to what could be a number of different, interesting applications. Note that the S7600A ONLY runs at 3.3 Volts.

The circuit used for this application is in pdf format and can be seen Here.

The bill of materials for this application is listed in the table below. Note that the prototype was built on the Seiko ISA developer's card which avoided the need for coming up with a method of connecting the SMT S7600A to a wire wrap or point to point prototype card.
