Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

Now let's look at the pinout for the Arduino Uno R4 WiFi development board. As you can see it is very similar to the Uno R3 development board but with each pin with more functions. It also provided ...

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 ...

Arduino UNO R4 WiFi. Arduino UNO R4 specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash; Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 ...
