Hi - I just purchased one of these boards from you today to explore for data logging - we want to record at set intervals - say every 5 minutes for say 2 minutes or similar (adjustable) and have the recordings time stamped. I will want these to run un-attended in the field on a battery, so I will want to turn off everything not necessary - for instance I imagine the Bluetooth is cool for programming? but would not be necessary for my application. I am wondering what the maximum SD card size is that I can use on the board and what codec is used. I need good quality audio so would look to keep at 44.1/16 but mono. I am wondering if there is already some code floating around that does this kind of thing that I could alter and or if people have experience of this kind of deployment. I also wonder what the current draw is when any unnecessary extensions are disabled for long term applications. Thanks in advance.
ps. I bought your card to test as I was not happy with the sound quality of the Teensy audio card
