PicIgate - APRS internet RX gateway with PIC24FJ64 microcontroller
The PicIgate started
as a self-study project to learn deeper the TCP/IP protocoll. The basis
of the software is the Microchip Tcp/Ip stack C library.
Hardware details and functions:
16 bit microcontroller - handling ethernet and internet, aprs
filtering, telemetry, beacon,LCD display,telnet and webserver
PIC16F88 - Packet radio tnc. Connected to PIC24 via serial link. AX25 - ASCII packet translator.
TCM3105 - 1200/2200 Hz FSK modem
ENC28J60 - Ethernet to SPI interface chip
PicIgate is a cheap solution if you don't want to use a computer for aprs gateway.
You need provide only 1 Watt for operation. (solar cell or accu)
