It retains the familiar 5V operating voltage and pinout, making it a direct upgrade for most UNO R3 projects while offering more memory, faster processing, and modern connectivity. This official board is manufactured in India under Arduino’s license, ensuring genuine quality with local availability.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrocontroller\u003c\/td\u003e\n\u003ctd\u003eRenesas RA4M1 (ARM Cortex-M4)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDigital I\/O Pins\u003c\/td\u003e\n\u003ctd\u003e14 (6 PWM)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAnalog Input Pins\u003c\/td\u003e\n\u003ctd\u003e6 (14-bit ADC)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlash Memory\u003c\/td\u003e\n\u003ctd\u003e256 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSRAM\u003c\/td\u003e\n\u003ctd\u003e32 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-pi-zero-w-mqtt-home-sensor-hub\"\u003eHome automation hub with relay control and sensor monitoring\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-line-following-robot\"\u003eLine-following or obstacle-avoidance robot\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-sd-card-data-logger\"\u003eEnvironmental data logger with SD card storage\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eLED matrix display driver using PWM on digital pins\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis board is pin-compatible with the original UNO R3 form factor, so most 5V Arduino shields and sensors work without modification. It integrates seamlessly with the Arduino IDE 2.x and can be programmed via the USB-C port. Common pairings include breadboards, motor drivers, and I2C\/SPI modules operating at 5V.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eAlways connect the board to a stable 5–12V power source via the barrel jack or USB-C. Digital I\/O pins can source up to 20 mA each; for higher loads, use transistors or relays. For I2C communication, pins A4 (SDA) and A5 (SCL) are default—no external pull-ups needed as the RA4M1 has internal ones.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno R3 shields?\u003c\/summary\u003e\u003cp\u003eYes, the R4 Minima maintains the same pinout and 5V logic as the Uno R3, so most shields operate correctly. However, note that the R4’s I2C pins are on a dedicated header (A4\/A5 still work), and the 3.3V regulator has a higher current limit.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use the Arduino IDE to program it?\u003c\/summary\u003e\u003cp\u003eAbsolutely. Install the latest Arduino IDE 2.x, add 'Arduino Uno R4 Minima' from the Boards Manager, and you can start coding immediately.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the board come with a USB cable?\u003c\/summary\u003e\u003cp\u003eThe board is typically sold without accessories.
