Arduino nano pinout icsp11/2/2022 ![]() ![]() While it is programmed to ignore malformed data (i.e. For the following half-second or so, the bootloader is running on the Nano. #ARDUINO NANO PINOUT ICSP MAC OS X#When the Nano is connected to a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). When this line is asserted (taken low), the reset line drops long enough to reset the chip. One of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega328 via a 100 nanofarad capacitor. Rather than requiring a physical press of the reset button before an upload, the Arduino Nano is designed in a way that allows it to be reset by software running on a connected computer. The Arduino software includes a Wire library to simplify use of the I2C bus. The ATmega328 also support I2C and SPI communication. ![]() A SoftwareSerial library allows for serial communication on any of the Nano's digital pins. The RX and TX LEDs on the board will flash when data is being transmitted via the FTDI chip and USB connection to the computer (but not for serial communication on pins 0 and 1). The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Arduino board. An FTDI FT232RL on the board channels this serial communication over USB and the FTDI drivers (included with the Arduino software) provide a virtual com port to software on the computer. It has more or less the same functionality. The ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. Flash memory: 32 KB, of which 2 KB is used by bootloader.Digital I/O pins: 14 (6 optional PWM outputs). ![]()
