Hello everybody! I am building a battery-powered sensor node based on Xenon board. The sensor that I NEED(really, no other option due to specs) is working on 5V and uses I2C and consumes 5ma during reading. I also want to mention that the node will read the sensor every 5 minutes, publish the value to the cloud and go to sleep(System.sleep).
For a start I got this board from sparkfun. Its a Logic Level Converter and also has voltage regulator. My questions are:
1.Is there a better board with Enable pin, so I can turn off the voltage regulator during sleep?
2.Is there a single chip that is able to convert both logic levels and has voltage regulator?(I would need this for the mass production version)
3.Can someone share experience with using Xenon on batteries with 5V sensor?
Thank you in advance!
