Measure AC voltage using analog pins in M16 v1 board

[homeassistant144]

I am currently using the M16 board to measure current within my house. I would also like to record real time data for 220v AC voltage using this same board. Is it possible to use the analog pins available on this board to measure 220v AC voltage with the help of esphome?

sorry, detect AC220v voltage need use M16v2 board.
it's not easy, only connect to analog input port, there is CT sensor circuit for monitor voltage.
