The difference between Arduino uno R4 minima and the wifi version
Both ArduinO UNO R4 boards adopt the Renesas Electronics RA4M1 processor, adopt the Arm Cortex-M4 architecture, increase the clock frequency to 48MHZ, and have 32KB of RAM and 256kB of flash memory built-in. The on-board peripherals are very rich, including a 12-bit DAC, CAN bus and operational amplifier. The working voltage remains at 5V, but the input voltage range has been expanded to 24V to accommodate more external device connections, such as multiple motors, LED light strips and drivers. And an Owiic connector has been added to facilitate the connection of the corresponding sensors and accessories.

Supporting HID function can simulate mice, keyboards and even game controllers. The USB connection interface has been upgraded to the widely used USB-C interface.
The Arduino UNO R4 Minima improves the clock speed, increases the memory and storage space, adds support for various peripherals, and adds the input voltage function to meet the requirements of various peripheral devices.
The ArduinO UNO R4WiF is equipped with the Essif ESP32-S3 chip from Lexin Technology. It not only provides Wi-Fi and Bluetooth connections, but also has a powerful microprocessor with a clock speed of up to 240MHZ, 512KB of SRAM and 384KB of ROM. It also features an OFF pin for turning off the development board, as well as an integrated real-time clock (RTC) and a VRTC pin for powering the RTC. In addition, the R4WiFi board features a 12x8 red LED matrix, which can be used for drawing patterns or displaying information.
Therefore, the Arduino uno R4 minima is suitable for makers who pursue high cost performance and do not need more additional functions, while the Arduino uno R4wifi version is suitable for makers and educators who pursue a high-performance version.
