I'm working on additional hardware for the freerunner. Currently I try to add a digital compass and (if possible) a treeaxial gyroscope. Everything should fit inside the case.
Update: the third version is available! See Freerunner Navigation Board v3
- Drivers are available from http://gitorious.org/freerunner-navigation-board
- Schematics and PCB-Layout files are available from [here].
