step motor module for encoder..

[cepics]

Hi all, is it possible read this encoder with this module?
ENCODER TEARDOWN
I would like to connect three encoder to the three motor ports.....

is it possible to modify this sketch for M5Stack?

#define BAUDRATE 100000  // oder  100000 115200
#define SERIALPORT Serial  // - uncomment this line if using an arduino based board with more than one HW serial port
