When I discovered the MMC2IEC / SD2IEC project by chance back in 2009, it made me dig up again my soldering iron and electronic components after many years of disuse. I built myself one of those devices on a prototyping board and had a lot of fun doing so. It was the first time that I got involved with micro controllers and I learned a lot in the process.
Now, many years and projects later, I was looking for an excuse to try out KiCAD and to learn how to design my own boards using it. I had already ordered a small PCB I found on the net as a proof-of-concept to see if the Gerber files I produce would result in working boards. When they turned out just as expected I was eager to create something myself. This was the perfect opportunity to revisit the subject and make myself a brand new SD2IEC.
I wanted the design to be based on Shadowolf’s latest version but also make my own additions and changes:
- The board should be able to tap into the cassette port of the C64 for power supply.
- It should be board for external use with proper connectors just like my first build.
- All components should be cheap to buy from Chinese suppliers.
So, this is the first prototype of what I came up with. I call it the “SD2IEC pluggable”:
