The ability to convert data from serial to parallel, and from parallel to serial, using shift registers. An on-chip bit rate (baud rate) generator to control transmit and receive data rate. Handshake lines for control of an external modem, controllable by software. An interrupt function to the host microprocessor.
It is fitted with a Lipo charge controller and 12 Grove sockets for plug and play prototyping. It runs at 3.3 V and 8 MHz. It also comes with a DS3231 Real Time Clock and 16 Mbit serial flash for data logging. Its "bee" socket can use a range of different modules, like Xbee, RFbee, Bluetoothbee and GPRSbee to make the board communicate.
The most well-known options are speed, number of data bits per character, parity, and number of stop bits per character. In modern serial ports using a UART integrated circuit, all these settings can be software-controlled. Hardware from the 1980s and earlier may require setting switches or jumpers on a circuit board.
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
Serial communication on pin D0 (RX) and pin D1 (TX). used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip. By sliding the switch (S1), RX/TX pins can be re-routed to Bluetooth UART connector. Linduino One Linear Technology Corporation [60] Yes ATmega328 16 MHz

The number of data and formatting bits, the presence or absence of a parity bit, the form of parity (even or odd) and the transmission speed must be pre-agreed by the communicating parties. The "stop bit" is actually a "stop period"; the stop period of the transmitter may be arbitrarily long.
