Power
There are two primary ways to power the SparkFun Real Time Clock Module - RV-8803 (Qwiic). The best and easiest way is through the Qwiic
Connectors on either side of the board. When used with any of our Qwiic-enabled boards or our Qwiic Shields, this voltage will be 3.3V. The other power
input is the 3.3V pin broken out. The board also includes a 3V 47mAh battery in the 12mm coin cell battery holder on the back for backup power.
