AT89C51 – 8051 SBC

As the Dutch TV commecial says… “A little bit of myself and a little bit of… “. My Home-brew AT89C51 Eurocard SBC based on an old Elektor design with some extensions. Flash interface to support Atmel’s “Flip”. As well as some external memory so that also plain 8051 and 8031’s can be used. The AM29F040 is used as I had a whole pile of these.

Inspired by Inspired by Francesco’s design, an old Elektor (Dutch elektronics magazine) and a design I made myself in the past a new Eurocard format design, with buffered outputs , RAM , EEPROM so that it can also fit the 8051 and 8031’s (ROMless). For Francesco’s design see his Facebook group :
