Each I\/O pin of the Arduino Nano can source or sink around 40mA of current.\u003c\/p\u003e\n\u003cp\u003eThis board operates at a voltage of 5V.

It formally defines the signals connecting between a DTE (data terminal equipment) such as a computer terminal, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem. The RS-232 standard is commonly used in computer serial ports. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the physical size and pinout of connectors. The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997.\" From \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/RS-232\" rel=\"nofollow\" target=\"_blank\"\u003eWikipedia\u003c\/a\u003e\n\n\u003ch4\u003eSPECIFICATION\u003c\/h4\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e4 pin connector -
