This Arduino UNO project involves using a SIM800H module for power surveillance and sending SMS alerts in case of a power outage or restoration. Hardware Connections: SIM800H Module: • BAT: Not ...

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

RA4M1-R4 core “clone” board (left) vs Arduino UNO R4 Minima (right) Some of the changes include a second row of yellow male headers, a 3.3V/5V switch for Arduino shields, an MD button to enter ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

However, the USB port doubles as a power port. To use it as such, you need a USB cable and a 5V power source. In the case of the Arduino Nano, a mini-B USB cable is required.
