- Arduino UNO R4 Minima
Arduino empowers makers’ creativity and passion for innovation with a robust new board that’s perfect for all users, from beginners to experts – allowing anyone to easily connect to the internet and create IoT projects.
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.
- Operating Voltage: 5V
- Memory: 256KB Flash / 32KB SRAM
- Input Voltage: 6-24V
- Clock Speed: 48 MHz
- Programming Port: USB-C
- MCU: RA41M1 from Renesas (Cortex M4)
- HID device (emulate a mouse or a keyboard)
- Improved power section (up to 24V through VIN)
- CAN bus
- DAC (12 bits)
- Op amp
Arduino UNO R4 Minima Product Help and Resources
Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

So so
This product is a great improvement over Arduino Uno R3 hands down But I give it a 2 because for all its features it is pretty much totally incompatible with Arduino Uno R3's ATmega328 MCU libs. Who builds a product that is not backward compatible? It probably should not be called "Arduino Uno R4" because it is totally incompatible with "Arduino Uno R3"
Sure, I get it, it uses a different MCU, but that is no excuse. I have gone to the Arduino forums for help and all I see is that they are still working on compatibility issues. I trust they will come-up with more backward compatible libraries.
Bottom line don't buy this product if you hope to use it with your UNO R3 projects. But if you are making new projects that don't use ATmega328 libs it may be a good product for that.
Best JUNK i have owned
NOTHING works! Won't program. No DFU USB Device found.
Try updating your Arduino IDE; any luck?
