This RS-485 module can be easily interfaced with Arduino. Let’s use the hardware serial ports of Arduino 0 (RX) and 1(TX) (In UNO, NANO). Programming is also simple just use the Serial.print() to ...

The Arduino Nano is a small, breadboard-friendly version of the Arduino platform. It is built around the ATmega328 microcontroller, similar to the Arduino Uno, and features the following key ...

The Arduino Nano uses a bootloader for handling programming the MCU, which requires the USB to serial bridge to be disconnected from anything that could interfere with the programming.

Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

This chip is what makes the Arduino Nano programmable. XTAL1, XTAL2: Clock inputs for the ATmega328. Pin Headers; S3, S4: Pin headers that provide access to the digital, analog, and power pins of the ...
