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 write to RS-485 and Serial.Read () to read from RS-485.

Arduino Nano 33 BLE Sense Hardware Overview At the first look of the board you can find a lot of components crowded on the top, most of which are sensors that I told earlier. But the main brain is ...

Some people on the internet hooked the TRX pin up to 5 volts and it seemed not to harm the module. I made a voltage divider out of a small 2K potentiometer that reduced the 5 volt of the arduino TX ...

The Nano is also a great choice when your code is pretty large. Since it has more usable flash memory than the Micro (30 KB vs 28 KB), it's better at handling long sketches.

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.

The Arduino Nano RP2040 Connect combines four big names from the embedded maker scene – Arduino, Raspberry Pi, ESP32 and Mbed OS – into a single module, which is quite interesting. It shows a will to ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
