**broken link removed**
this is my own developed 8052 development board
for working with this board
you only need sdcc C compiler ( it is free )
a 10 W transformator
and a serial cable
It has 8 optoizolated inputs ( can be 20 max )
5 relay output ( can be 12 max )
8x analog inputs
8K code memory
8K data RAM
8K serial EEPROM ( no example code yet )
1 x RS232 port ( RS485 optional )
all input output socket terminals
a free windows program for downloading application
and monitoring inputs is included
for volume purchase I can give very good price
