Power Output - Quectel SC200R Series Hardware Design

Coin Cell
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.
