Re: [44net] Making Packet Node with Pi ?

The Raspberry Pi can use a USB-to-RS232 serial adapter, as long as there are drivers for the adapter that work on the OS you are running on the Pi. Alternatively, there are pins on the GPIO header that are connected to a UART on the Pi’s board (pins 6, 8 and 10). With a voltage level converter (e.g. MAX3232) that can convert from the 0-3.3v on the Pi to RS232 levels (-12, 0, +12v), you can use those pins to communicate with a device that has an RS232 port.
