Raspberry PI has a port UART for communications in series TTL, that we should convert to the standard serial RS232 using a plate like the following to connect to our serial port.
Raspberry PI ina bandari ya UART PATANIFU kwa ajili ya mawasiliano katika mfululizo TTL, kwamba unapaswa kugeuza kwa kiwango serial RS232 kutumia sahani kama yafuatayo ili kuunganisha yetu Kituo tarishi tambulisho.
