Great comparison between the Sanguinololu and the SAV MK1 electronics
A must-read! My summary is that this design has solved all the issues that the Sanguinololu has, and provides a high-quality solution while keeping the cost low and providing many missed features:
- High speed USB connection
- Properly dimensioned current drivers
- Integrated SD card
- Integrated fan control FINALLY!!
