Arduino UNO is a microcontroller board based on the
ATmega328P.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

Arduino UNO R4
Arduino UNO R3 的 8 位微控制器
Arduino UNO R4 确实保留了 UNO 系列的众所周知的特性——标准外形、屏蔽兼容性、5V 工作电压、出色的稳健性——同时提供不少于 32 位 Cortex® - M4 和 3 至 16x增加时钟速度、内存和闪存。

Here at Arduino we are thrilled to announce a new, revolutionary revision of the iconic UNO board, which will expand the concept of the open-source brand’s most iconic and popular product while providing the maker community with a long-awaited update on performance and possibilities. The Arduino UNO R4 indeed preserves the well-known features of the UNO family – standard form factor, shield compatibility, 5V operating voltage, outstanding robustness – while offering no less than a 32-bit Cortex®-M4 and a 3-to-16x increase in clock speed, memory and flash storage.
This huge leap forward starts with a new processor by Renesas, a global leader in microcontrollers, analog, power and SoC products. While over 10 million users have enjoyed playing and working with Arduino UNO R3’s 8-bit microcontroller for more than a decade, the new RA4-series MCU will open up endless new project opportunities for more advanced makers, and bring the board up to speed with current standards.
The UNO R4 will come in two versions – UNO R4 WiFi and UNO R4 Minima – offering unprecedented performance and possibilities for the maker community.
The WiFi version comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike; while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.
In details, the new Arduino UNO R4 features the Renesas RA4M1 (Arm Cortex®-M4) running at 48MHz, which provides a 3x increase over the UNO R3. In addition to that, SRAM went from 2kB to 32kB, and flash memory went from 32kB to 256kB to accommodate more complex projects. In addition, following the requests from the community, the USB port was upgraded to the USB-C and maximum power supply voltage was increased to 24V with an improved thermal design. The board provides a CAN bus, which allows users to minimize wiring and execute different tasks in parallel by connecting multiple shields. Finally, the new board includes a 12-bit analog DAC.
All in all, Arduino UNO R4 is the answer to the requests for improvement and updates the developer and maker community has been advancing, making it easier than ever to get started with Arduino.

Arduino UNO R4 MINIMA
$20.00
https://store.arduino.cc/products/uno-r4-minima
The Arduino UNO R4 Minima (from here on referred to as UNO R4 Minima) is the first UNO board to feature a 32- bit microcontroller. It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0), which
embeds a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4's memory is larger than its predecessors, with
256 kB flash, 32 kB SRAM and 8 kB data memory (EEPROM).
The UNO R4 Minima board's operating voltage is 5 V, making it hardware compatible with UNO form factor
accessories with the same operating voltage. Shields designed for previous UNO revisions are therefore safe to use
with this board but are not guaranteed to be software compatible due to the change of microcontroller.

Arduino UNO R4 WiFi
$27.50
https://store.arduino.cc/products/uno-r4-wifi
The Arduino® UNO R4 WiFi is the first UNO board to feature a 32-bit microcontroller and an ESP32-S3 Wi-Fi®
module (ESP32-S3-MINI-1-N8). It features a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0),
based on a 48 MHz Arm® Cortex®-M4 microprocessor. The UNO R4 WiFi's memory is larger than its predecessors,
with 256 kB flash, 32 kB SRAM and 8 kB of EEPROM.
The RA4M1's operating voltage is fixed at 5 V, whereas the ESP32-S3 module is 3.3 V. Communication between
these two MCUs are performed via a logic level translator (TXB0108DQSR)
