Arduino UNO R4 Development Board

The newly launched Arduino UNO R4 comes in two versions: UNO R4 WiFi and UNO R4 Minima. It is powered by the Renesas RA4M1 (Arm® Cortex®-M4) microcontroller, operating at a speed of 48MHz, which is three times faster than the UNO R3. The SRAM has increased from 2kB in R3 to 32kB, and the flash memory has expanded from 32kB to 256kB to accommodate more complex projects. Additionally, the USB port has been upgraded to USB Type-C, and the maximum power supply voltage has increased to 24V. The new board also features a 12-bit analog DAC and a CAN bus, allowing users to minimize wiring and perform different tasks by connecting multiple expansion boards.
