Alright, I know that there are a lot of discussions on here about this topic, and I have read through them, but I am still a bit confused about this line in the manual: NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY. NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
I am working on a project that will involve me using multiple sensors with the BBB that are powered from another source. One of those sensors is a GPS that spits out data as long as it is powered, but the others only send data after they have received a request. Here are my questions: 1. Based on that statement, it is my understanding that if the GPS I'm using is powered and the BBB is not, then the BBB will be damaged. Is this accurate? 2. What if the board and all the sensors are powered from the same source controlled by a single switch? Will this damage the board when I flip on the switch? 3. What if I power all the sensors from the board itself so that it is impossible for them to receive power before the board does? Will this damage the board? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
