Adc Interface; Network Status Indication - Quectel UC200T-EM Hardware Design

3.13. ADC Interface*

UC200T-EM module provides two analog-to-digital converters (ADC). In order to improve the accuracy of
ADC, the trace of ADC should be surrounded by ground.

3.14. Network Status Indication

The network indication pins can be used to drive network status indication LEDs. The module provides
two pins which are NET_MODE and NET_STATUS. The following tables describe pin definition and logic
level changes in different network status.
