Arduino UNO R4 Minima

Introducing the Arduino UNO R4 Minima, a groundbreaking addition to the UNO board family. This new launch boasts impressive features, starting with its 32-bit microcontroller. Powered by the RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0), which houses a 48 MHz Arm Cortex-M4 microprocessor. <h4><strong>Pin Configuration:</strong></h4> The UNO R4 Minima offers expanded memory capabilities, including 256 kB flash, 32 kB SRAM, and 8 kB data memory (EEPROM). Operating at 5 V, this board ensures compatibility with UNO form factor accessories designed for the same voltage. While previous UNO shields can be used, software compatibility may vary due to the microcontroller change. Experience the UNO R4 Minima’s cutting-edge performance and enhanced features today. <hr /> <h4><strong>Features:</strong></h4> <ol> <li>32-bit development board, being previously based on 8-bit AVR</li> <li>The board features the standard 14 digital I/O ports, 6 analog channels</li> <li>dedicated pins for I²C, SPI and UART connections.</li> <li>Larger memory: <ol> <li>8 times more flash memory (256 kB)</li> </ol> </li> <li>16 times more SRAM (32 kB).</li> <li>Easy power management: <ol> <li>The UNO R4 has a barrel jack connector and supports input voltages from 6-24 V.</li> </ol> </li> <li>This connector is widely popular and removes the need for additional circuitry required to step down the voltage.</li> <li>Cross compatibility: <ol> <li>The UNO form factor automatically makes it compatible with hundreds of existing third-party shields and other accessories.</li> </ol> </li> </ol> <strong>Note: For detailed technical Specifications go through Datasheet in the attachment section</strong> <hr /> <h4><strong>Package Includes:</strong></h4> 1 x Arduino UNO R4 Minima Board     <h1 class=""entry-title"">Arduino UNO R3 VS R4 – Differences Explained in Detail</h1> <table> <tbody> <tr> <td><strong>Difference</strong></td> <td><strong>UNO R3</strong></td> <td><strong>UNO R4</strong></td> </tr> <tr> <td><strong>Microcontroller</strong></td> <td>8-bit ATmega328p</td> <td>32-bit Renesas RA4M1</td> </tr> <tr> <td><strong>Clock frequency</strong></td> <td>16 MHz</td> <td>48 MHz</td> </tr> <tr> <td><strong>Wireless module</strong></td> <td>NO</td> <td>*ESP32-S3 Mini</td> </tr> <tr> <td><strong>Memory</strong></td> <td>2KB SRAM, 32KB FLASH, 1KB EEPROM</td> <td>256 kB Flash, 32 kB RAM *ESP: <em>384 kB ROM, 512 kB SRAM</em></td> </tr> <tr> <td><strong>RTC</strong></td> <td>NO</td> <td>YES</td> </tr> <tr> <td><strong>Input voltage (VIN)</strong></td> <td>6-20 V</td> <td>6-24 V</td> </tr> <tr> <td><strong>Digital I/O pins</strong></td> <td>14</td> <td></td> </tr> <tr> <td><strong>Analog input pins</strong></td> <td>6(10-bit)</td> <td>6(14-bit)</td> </tr> <tr> <td><strong>PWM pins</strong></td> <td>6(8-bit)</td> <td>6(12-bit)</td> </tr> <tr> <td><strong>DAC pin</strong></td> <td>NO</td> <td>1(12-bit)</td> </tr> <tr> <td><strong>CAN Bus</strong></td> <td>NO</td> <td>1</td> </tr> <tr> <td><strong>Dimensions</strong></td> <td>68.58 x 53.44 mm</td> <td>68.6 x 53.4 mm</td> </tr> </tbody> </table>
