Hi
that is the fine thing of low cost development systems; when you see your device is to weak for your application you have to switch to a bigger environment. You then not only have to install the software again, your hardware is also obsolete!
For this reason i prefer a modular design. A long, long time ago i have begun to build up my modular development system. First based on the ECB-Bus (CP/M80, Z80) and later my own "standard". This includes a port connector with the bits always on the same location as well as some power pins for powering the "addons". I am now able to switch between different MPU's by changing the MPU module. That works for the HCS08, HC08 and RS08 family, even the software can be modified thanks to EBS08!
I am wondering why the whole word is designing EVB's for a single MPU (a lot of repeated work for layouting and testing) with solder pads on it (they are looking ugly after a short time!!), when it could be done much easier.
The first pic is showing a GB32 module with the baseplate and two RS232 converters while testing the software for a milling machine and the second pic is the KAx module with the OSBDM+E and the porttester during EBS08R testing.
