In our experiences with several universities at Taiwan, there are three cases to break RoBoard:
1. plug the power supply inversely. (RoBoard has no protection for this.)
2. short the Vxx pins of high voltage (>> 5V) with any signal pin of COM ports, SPI, and I2C.
3. put uncarefully some conductor on RoBoard so that some components are shorted.
The ESD is a new issue for us, and we need to make some experiment to verify this.
