  • I got an email from the manufacturer stating that the I/O pins are 3.3v but the power supplied to the unit should be at least 4.6v, be careful all those planning to use a 5V TTL for the I/O, I also understand from the manufacturer ADH that unit is less reliable if powered at 3.3V

    Could I suggest that Sparkfun avoid using the term “5V TTL”?.

  • The documentation says that I/O pins are 3.3v can you confirm that 5v logic levels are safe?

No public wish lists :(
