Configuring Modes
M0 and M1 are used to set the modes of the module. There are four modes:
normal both M0 M1 connected to Gnd.This is normal transparent mode in which communication happens.
Sleep and configure mode both M0 M1 are pulled high or left floated.
other 2 modes are wake-up & power-saving.

Power source best supported @ 5v.
But Rx Tx levels are at 3.3v. So you need a level shifter while connecting to Arduino.

The AUX pin serves as a flag for checking if the data has been sent or when data has been received. It’s also used to check if the module is still in self-check procedure which happens during power-on and exit from sleep mode.

When the module is idle, the AUX pin stays high. If there is data is to be sent, the AUX pin stays low 2-3 ms prior to the data being sent to the transmit buffer. The AUX pin goes back to high if the transmit buffer is clear (i.e., the data has been sent wirelessly). Similarly, the AUX pin goes low when there is data on the receive buffer.
