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.

MyMed Face Oil
Style: Dermaplaning Oil
As an esthetician, I use this oil to dermaplane clients. It is lightweight, almost like a dry oil but doesn't dry down. It does give good slip without being too much. It's not too oily and has not caused burns or breakouts in my clients. You may find yourself pulling too much oil from the skin when dermaplaning but add a drop more if needed for slip and you should be fine. Its scent is light and pleasant, also. So far, so good!

Perfect for Smooth Dermaplaning!
Style: Dermaplaning Oil
This oil is amazing for dermaplaning! It provides the perfect glide for my razor without irritating or damaging my skin. The ingredients—jojoba and squalane—are some of my favorites, and my skin has been loving them. Every time I use this, my skin feels softer, smoother, and more nourished. The more I use it, the better my skin looks. If you dermaplane regularly, this is definitely a must-have!

INACCURATE DESCRIPTION
Style: Dermaplaning Oil, Style: Dermaplaning Oil
the product description reads, “ Dermaplane Oil for Smooth Razor Glide, with Squalane & Vitamin E, Face Oil for Dermaplaning Oil, All-Natural Formula, Dermaplane Spray Oil, Non-Greasy, Suitable for Sensitive Skin 3.21 Fl Oz by MyMed” However, the product I actually received is one box of 1.7 fl oz. Not worth the hassle of returning. Just want others to be aware of the product error.

Silky smooth for dermaplaning
Style: Dermaplane Oil
This is a very effective dermaplaning oil that isn't greasy and allows my razor to glide over my skin smoothly. After use, my skin feels better hydrated and smooth. The ingredients are natural and good for the skin, and I've noticed a difference when I use it. I highly recommend this natural oil for dermaplaning.

Wonderful but Sharp!
Size: #14R, Style: Pack of 20
These things are legit! This is not the typical ones you find in Walmart, Ross, TJMaxx etc. This is a true blade that will indeed do authentic dermaplaning. That said, be EXTREMELY careful with this as you can easily cut yourself. I highly recommend to anyone experienced but if you have no experience I would opt for the typical ones you can buy in the stores previously mentioned.
