Sure, you can send it back to the address you typed, and we will take a look at the board to see if it’s still functioning.
One of the vulnerabilities of Pi or BBB is that shorting GPIO pins can easily cause damage to the board. Arduino is much more robust in this aspect. Perhaps in the next revision I should consider adding protection circuitry to the GPIO pins to avoid shorting. Sometimes a simple resistor connected in series is sufficient to provide the protection.
