Hello…real excited about this product. Have used an Arduino on a few projects (build a ultrasonic sensor for example). I needed something for data logging with RTC without soldering (no thanks Adafruit).
Anyways I need to send this out in the field to measure vibrations and log the data. It needs to be out there for 2 weeks at a minimum. I was wondering if anyone knows of any battery solutions that might work. The sensor runs on 5 volts. Any ideas?
Also I was wondering what is the max SD card I can use?
