Overview

The Arduino UNO R4 WiFi combines the processing power and exciting new peripherals of the RA4M1 microcontroller from Renesas with the wireless connectivity power of the ESP32-S3 from Espressif. On top of this, the UNO R4 WiFi offers an on-board 12x8 LED matrix, Qwiic connector, VRTC, and OFF pin, covering all potential needs makers will have for their next project.

With the UNO R4 WiFi, you can easily upgrade your project and add wireless connectivity to expand the reach of your current setup. If this is your first project, this board has everything you need to spark your creativity.

 

Let's explore what the UNO R4 WiFi has to offer:

  • Hardware compatibility with UNO form factor: The UNO R4 WiFi maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3, ensuring a seamless transition for existing shields and projects.
  • Expanded memory and faster clock: The UNO R4 WiFi boasts increased memory and a faster clock speed, enabling more precise calculations and effortless handling of complex projects.
  • Extra on-board peripherals: The UNO R4 WiFi introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, providing expanded capabilities and design flexibility.
  • Extended 24 V tolerance: The UNO R4 WiFi supports a wider input voltage range, allowing seamless integration with motors, LED strips, and other actuators using a single power source.
  • HID support: With built-in HID support, the UNO R4 WiFi can simulate a mouse or keyboard when connected to a computer via USB, making it easy to send keystrokes and mouse movements.
  • Wi-Fi® and Bluetooth®: The UNO R4 WiFi hosts an ESP32-S3 module, enabling makers to add wireless connectivity to their projects. Combined with the Arduino IoT Cloud, makers can monitor and control their projects remotely.
  • Qwiic connector: The UNO R4 WiFi features a Qwiic I2C connector, allowing easy connection to nodes from the extensive Qwiic ecosystem. Adapter cables also enable compatibility with sensors and actuators based on other connectors.
  • Support for battery-powered RTC: The UNO R4 WiFi includes additional pins, including an "OFF" pin to turn off the board and a "VRTC" pin to keep the internal Real-Time Clock powered and running.
  • LED matrix: The UNO R4 WiFi incorporates a bright 12x8 red LED matrix, ideal for creative projects with animations or plotting sensor data, eliminating the need for additional hardware.
  • Diagnostics for runtime errors: The UNO R4 WiFi includes an error-catching mechanism that detects runtime crashes and provides detailed explanations and hints about the code line causing the crash.

With all these features packed into the well-known UNO form factor, now is the perfect time to upgrade your project or embark on your maker journey. The UNO R4 WiFi offers unparalleled versatility and possibilities for makers of all levels.

DO NOT PUT IN DRYER
Color: Cream&grey, Size: 60"x80"
Very soft, very comfortable, very warm, sheds a lot at first. 9/10 for initial impression. So how do you wash it? The instructions say take it to a professional dry cleaner which costs more than the blanket, so that option is out. I've been looking everywhere and everyone says something different, I've ruined two blankets trying to figure it out how to clean them. DO NOT PUT IN YOUR DRYER WITH HEAT, EVER, PERIOD. I ruined my second blanket by putting it in the dryer for just 7 minutes on 'delicate' heat, just don't do it. Even using no heat in the dryer will cause the material to become slightly more abrasive after each cycle. MACHINELESS AIR DRY ONLY. The faux fur has an insanely low fraying point and even getting it moderately warm causes it to become abrasive and have a harsh tangled 'dog blanket' feel to it that is permanent. COLD WASH ONLY ON DELICATE. This seems to have little to no effect on the quality of the blanket. Use high quality detergent with little to no additives for delicates and a laundry bag. Fabric softeners are a big NO, they will shorten the life of your blanket substantially. For colors, The Cream and Grey and Yellow and Grey are very nice and picture accurate. The Camal was far darker than the images would have you believe and it has a greenish copper tint to it. The Ivory looks awful with how they brushed the tips.

My Favorite Blanky
Color: Yellow&grey, Size: 60"x80", Color: Yellow&grey, Size: 60"x80"
The color of the yellow/grey is exceptional. The blending and pattern of the two colors makes for a very realistic looking pelt and the colors go with an extensive variety of other colors you may have in your home. In a couple of spots you could see little clumps where the fur was sticking out further than the rest, almost like it was trying to shed, but I just took scissors and cut the little tuffs to be even with the rest of the fur. Never once has it actually shed. It holds smells really well so washing it on a delicate cycle with those scent booster beads and then putting it in the dryer on the Air Dry setting creates this magical scent that fills an entire room. I have issues with a lot of textures so I’m very particular about my fabrics and furs and I can tell you this blanket feels like pure bliss and does not give me sensory overload or an icky feeling. It’s a great weight as well, id say it’s a medium-heavy blanket. It’s exactly what I was looking for. I have had this blanket for about a year now and the quality is definitely worth it. It’s held up against 3 big dogs, my toddler, and my newborn and it still looks like it just got delivered to me. Personally I thought the blanket was going to be bigger, but I am still content with the size. it’s gone from my couch to my bed and fits both perfectly. I love it on both. I feel that for the price the blanket could have been bigger but other than that, it was worth the money.
