The MSB-IoT is a platform designed by FU Berlin for research. I don't know if the design is open, but you could try to contact Dr. Achim Liers  who designed the board"
Thanks. I'm very late also -- I found your response in the archives -- missed emails those days, I guess.

Do I understand your question correctly that you want to know the impact of amount of memory and clock speed on energy consumption and performance? "
I am simply looking for a guide to making a platform that will run RIOT with the recent stable release without running out of memory. After that, I am interested in studying RIOT code to learn about easy ways to sleep and slow the clock for power savings while still listening with a 900MHz radio.
Then maybe I can become more of a contributor of code and open hardware modules.
