Gpio Interfaces - Quectel BG95 Series Hardware Design

Table 23: Characteristics of ADC Interfaces
Parameter
ADC0/ADC1 Voltage Range
ADC0/ADC1 Resolution
ADC0/ADC1 Sampling Rate
NOTES
1. ADC0 and ADC1 cannot be used simultaneously. BG95 supports using of only one ADC interface at
a time: either ADC0 or ADC1. Currently only ADC0 is enabled, and ADC1 will be enabled in the next
hardware design version.
2. ADC input voltage must not exceed 1.8V.
3. It is prohibited to supply any voltage to ADC pin when VBAT is removed.
4. It is recommended to use resistor divider circuit for ADC application, and the divider resistor accuracy
should be no less than 1%.

3.17. GPIO Interfaces

The module provides six general-purpose input and output (GPIO) interfaces. AT+QCFG= " gpio " *
command can be used to configure corresponding GPIO pin's status. For more details about the AT
command, please refer to document [2].
