Deep Sleep Consumption <20uA!

Deep Sleep Consumption

Q: Ok, but how does that translate to battery life?

A: Well if you had this paired with a 1500mah LiPo battery, turning on once a day and sending a sensor reading over MQTT it would last for over 5 years!

NOTE: the Bee S3 does NOT have LiPo charging capabilities. to re-charge a battery you will need an external battery charging option.
