5.7.3 Serial Ports
The Telit ME310G1 module is includes 3 Asynchronous serial ports:
• Asynchronous Serial Port (USIF0)
• Asynchronous Serial Port (USIF1)*
• Auxiliary Serial Port
You may design various serial port configurations on the OEM hardware.
The common are designs are:
• RS232 PC com port
• Microcontroller UART @ 1.8V (Universal Asynchronous Receive Transmit)
• Microcontroller UART @ 5V or other voltages different from 1.8V
Depending on the serial port type on the OEM hardware, a level translator circuit may be
required to operate the system. The serial port on the module is CMOS 1.8.
Note: *The USIF1 is currently NOT supported by ME310G1 firmware.
