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.

Great-Tasting Protein Shake With Fresh Product Dates and Excellent Nutrition
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
I picked up this Premier Protein chocolate shake 12-pack mainly as a convenient daily protein option, and overall the quality has been excellent. The chocolate flavor tastes very good without being overly sweet, and the texture is smooth compared to many protein drinks that can feel chalky or heavy. The 30 grams of protein also make it very practical for quick meals, post-workout use, or busy days when preparing food is not convenient. One thing I appreciated is that the product arrived with fresh expiration dates, which is important when buying protein drinks in bulk. The packaging was also in good condition, and the bottles were easy to store and carry. The nutritional balance is another strong point, especially with the added vitamins and minerals included without extra added sugar. Compared to many other ready-to-drink protein shakes, this one feels lighter while still being filling and satisfying. In terms of value for the money, it feels like a very good purchase considering the quality, nutrition content, convenience, and freshness. Overall, a high-quality protein shake with excellent taste, fresh product dates, strong nutritional value, and very good everyday convenience. It can also be mixed with other flavors.

What's small and powerful and full of protein?
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
This is better than expected - filling - chocolate-milkish taste - lots of protein - only o few calories - good for times you want to eat less but still have energy - It is a good product to have on hand - it is filling - this is not exciting but rather useful in a busy life -when you don't want to cook, before a medical procedure or any situation where less is more. The taste is good enough - best ice cold - I would recommend this product.

Good taste, No sugar, Low Carb, High Protein
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
Highly recommended, no sugar, low carb, high protein. This exceeded my expectations. It tastes good chilled, much better than other forms of protein supplements. I have never had a ready mixed protein shake, so I was hesitant about buying it. Protein powder always tasted too strong & not good after taste. Although there are some Ok Protein bars, they do mostly have undesirable taste & not good after taste.
