If RTC is ineffective, it can be synchronized through the network after the module is powered on. The
recommended input voltage range for VRTC is 2.0
–3.25 V and the recommended typical value is 3.0 V.
3.7. Power Output
SC200R series module supports output of regulated voltages for peripheral circuits. During application, it
is recommended to connect a 33 pF and a 10 pF capacitor in parallel in the circuit to suppress
high-frequency noise.
