Hardware Overview
The heart of this breakout is the RV-8803 Real Time Clock module from Micro Crystal. In this section we'll cover most of the features and characteristics
of the RV-8803 and this breakout but if you are looking for a more thorough synopsis of the RV-8803, take a look through the Application Manual . The
table below lists some of the operating characteristics of the RV-8803.
Characteristic Value
Operating Voltage Range 1.5V - 5.5V
Time Accuracy (Temp. Compensated -40° to +85°C) +/-3 ppm
Time Accuracy (Temp. Compensated +85° to +105°C) +/-7 ppm
Current Consumption 240 nA (Typ.) to 350 nA
I C Address 0x64
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.
