Indication Signal - Quectel EC200A Series Hardware Design

For more details about the AT command, please refer to document [2].
The resolution of the ADC is up to 12 bits. The following table describes the characteristic of the ADC
interface.

NOTE
1. The input voltage of ADC should not exceed its corresponding voltage range.
2. It is prohibited to supply any voltage to ADC pin when VBAT is removed.
3. It is recommended to use resistor divider circuit for ADC application and the divider resistance should
not exceed 100K.
