Figure34: ISINK reference circuit
Note: The sinking current can be adjusted to meet the design requirement through the AT
command “AT+ CLEDITST =<0>, <value>”.The “value” ranges from 0 to 8, on behalf of the
current from 0mA to 40mA by 5mA step.
3.15.2 ADC
MODULE has 2 dedicated ADC pins named ADC1 and ADC2.They are available for digitizing
analog signals such as battery voltage and so on. These electronic specifications are shown in the
following table.

pins, for more details, please refer to document [1].
3.15.3 LDO
MODULE has a LDO power output, named VDD_AUX. its output voltage is 2.85V by default,
Users can switch the LDO on or off by the AT command “AT+CVAUXS” and configure its output
voltage by the AT command “AT+CVAUXV”.
