Your user-friendly, accessible UNO just took a quantum leap forward: Arduino UNO R4 is a 32-bit microprocessor offering more speed, memory, connectors and connectivity options than any version of the board before. Out of this world, and into the future. Arduino’s continued commitment to making technology accessible to everyone was the inspiration behind Arduino UNO R4 Minima: the new addition to the brand’s community-supported ecosystem offers powerful technology at an affordable price. Packing more computational power, memory and speed in the familiar form factor of the UNO at 5V operating voltage, it allows users to easily upgrade projects made with the UNO R3 or the Leonardo. What’s more, thanks to a RA4M1 microcontroller by Renesas, it can leverage two new off-the-shelf peripherals, CAN BUS and (12 bit) DAC: perfect for automation or audio projects. UNO R4 Minima is armed with a powerful 32-bit microcontroller courtesy of Renesas. Brace yourself for increased processing power, expanded memory, and a whole new level of on-board peripherals. The best part? Compatibility with existing shields and accessories remains intact, and there’s no need to make any changes to the standard form factor or 5 V operating voltage. Features of Arduino UNO R4 Minima board (Clone) Type-C: • Hardware compatibility with UNO form factor: The UNO R4 Minima retains the UNO R3’s form factor, pinout, and 5 V operating voltage. By utilizing the vast and distinctive ecosystem already developed for the Arduino UNO, guarantees a seamless transition for current shields and projects. • Expanded memory and faster clock: Prepare for more accurate computations and the capacity to manage challenging projects with ease thanks to the increased RAM and quicker clock. With more memory and a quicker clock speed, the UNO R4 Minima gives you the ability to complete difficult jobs with ease. • Extra on-board peripherals: A 12-bit DAC, CAN BUS, and OP AMP are just a few of the new on-board peripherals that the UNO R4 Minima offers. You have greater skills and design flexibility thanks to these extra parts. • Extended 24 V tolerance: The UNO R4 Minima now allows power supply up to 24 V and has a larger input voltage range. By using a single power supply, this enables smooth connection with motors, LED strips, and other actuators, simplifying your projects. • SWD connector: Every project needs to have a robust debugging process. Simply connect an external debugger to the UNO R4 Minima to monitor your system’s internal operations. Maintain control while gaining insightful knowledge. • HID support: When connected to a computer using a USB cable, the UNO R4 Minima may emulate a mouse or keyboard thanks to built-in HID (Human Interface Device) functionality. The usability and functionality of a computer are improved by this practical feature, which makes it simple to convey keystrokes and mouse movements to a computer. Overview of Arduino UNO R4 Minima board (Clone) Type-C: Block Diagram of Arduino UNO R4 Minima board (Clone) Type-C: Pinout of Arduino UNO R4 Minima board (Clone) Type-C: Power Pins Pin | Function | Description VIN | Input | Voltage input (6V to 24V) +3V3 | Output | 3.3V power rail +5V | Output | 5V power rail GND | – | Ground IOREF | Output | Reference voltage (5V) Digital GPIO Pins Pin | Function | Description D0-D13 | GPIO | General-purpose pins D3, D5, D6, D9, D10, D11 | PWM | Pulse Width Modulation D1/TX0, D0/RX0 | UART | Serial communication D13/SCK, D12/CIPO, D11/COPI, D10/CS | SPI | Serial Peripheral Interface D5/CANRX0, D4/CANTX0 | CAN | CAN Bus communication Analog Pins Pin | Function | Description A0-A5 | Input | Analog input pins A0 | DAC | Digital to Analog Converter A1, A2 | OPAMP | Operational Amplifier A4, A5 | I²C | I²C communication (SDA and SCL) Other Pins Pin | Function | Description BOOT | Mode | Mode selection Reset | – | Board reset AREF | Input | Analog reference voltage Operating Conditions & Power Supply Recommended Operating Conditions Symbol | Description | Min | Typ | Max | Unit VIN | Input voltage from VIN pad / DC Jack | 6 | 7.0 | 24 | V VUSB | Input voltage from USB connector | 4.8 | 5.0 | 5.5 | V TOP | Operating Temperature | -40 | 25 | 85 | °C Power Options The Arduino board offers multiple power supply options: • VIN Pin: Power can be provided through the VIN pin. • Barrel Jack: An alternative is to use the barrel jack. • USB-C Connector: The board can also be powered via the USB-C connector. When power is channeled through the VIN, the ISL854102FRZ buck converter efficiently steps down the voltage to 5 V. Both the VUSB and the barrel jack connector, along with the VIN pins, are directly linked to this ISL854102FRZ buck converter. When powering the board via USB, it’s worth noting that the RA4M1 microcontroller receives approximately ~4.7 V, a slight reduction due to the Schottky diode drop. Pin Voltage The UNO R4 Minima operates at 5V, and this applies to all the pins on the board with the exception of the 3.3V pin. This specific pin sources its power from the VCC_USB pin on the R7FA4M1AB3CFM#AA0. Notably, it is not linked to the buck converter. Pin Current Limitations The GPIOs of the R7FA4M1AB3CFM#AA0 microcontroller are designed to handle a maximum current of 8 mA. It’s crucial to avoid connecting devices that demand a higher current directly to these GPIOs. For powering external devices that necessitate greater power, such as servo motors, always opt for an external power supply.
