This Uno R4 Minima-compatible development board is a high-performance alternative to the classic R3 Uno, offering all the functionality of the official Arduino® UNO R4 Minima—at a more accessible price. It's perfect for makers, educators, and engineers looking for next-generation features while retaining compatibility with the Arduino ecosystem. Built around the powerful Renesas RA4M1 32-bit Arm® Cortex®-M4 processor, this board runs at 48 MHz and offers significantly more memory and processing capability than the older Uno R3. It maintains the same physical pin layout and 5 V logic, ensuring seamless compatibility with most shields and existing Arduino projects. Please note: This board is based upon the Arduino® R4 reference design. It is functionally identical and fully compatible with the Arduino® UNO R4 Minima in terms of hardware layout, software support, and development experience.Features: Processor: Renesas RA4M1, 48 MHz, 32-bit Arm® Cortex®-M4Flash Memory: 256 KBSRAM: 32 KBOperating Voltage: 5 VDigital I/O Pins: 14 (6 PWM-capable)Analog Inputs: 6UART: 1I2C: 1CAN Bus: 1USB Connection: USB Type-C® for power and programmingForm Factor: Same size and pinout as the classic UnoIDE Support: Compatible with the Arduino® IDE and libraries
