Hey guys,

did you ever wonder how to do a simple RS232 levelshifter for your connection between PC and microcontroller? No? Well, don’t wonder no longer.

I did a small layout which contains a two-channel RS232 level shifter with optional hardware handshake connection (CTS/RTS), selectable via jumper. If it is disabled, the RTS will be connected to the CTS which fakes a real hardware handshake. You can grab the complete package here.

Addionally, I finally managed to add some small stuff , so check out the other pages to see what has changed…

Regards,

Daniel
