Microchip PIC Ethernet Board with RS232 Interface US$10.00

Microchip PIC Ethernet Board with RS232 Interface

Ethernet Board & Web Server for Microchip PIC microcontrollers

Revision 2

The SBC45EC is a single board computer with 10 Mbs Ethernet and an RS232 interface for 44-pin PLCC PIC18Fxxx microcontrollers. It comes with a PIC18F452 CPU, a 24LC256 EEPROM for web pages, and with a demo of a Web Server installed. By using a terminal program, the demo web page can be replaced by a custom one with no programming required.

Typical applications include HTTP web servers, mail clients, Ethernet to RS232 interface converter, Ethernet to RS485 interface converters, remote control via web server, or protocol bridge applications -- Ethernet to USART, CAN, I2C, SPI etc.

It has been tested with the PIC18F452 and PIC18F458 44-pin PLCC PIC chips and the Microchip TCP/IP stack, but it also can be used with any other 44-pin PLCC PIC18 chips as long as there is enough Flash memory.
