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.

You can experience joy!
Format: Paperback, Format: Paperback
What is joy? How does it compare to happiness? From where does joy come? How can we experience joy every day despite the pain and sorrow that we all experience? Stasi Eldredge writes honestly and poignantly from places of pain and sorrow in her own life - but doesn't leave us there. She leads us into hope, into beauty and into a new depth of life in God. She teaches us how to cultivate joy in really practical - and achievable - ways. I was especially struck by her walking through St. Patrick's Breastplate - an ancient prayer - and how I can turn from a place of failure and shame based on my performance to the King and His character and hide myself in Him. "I need mercy, and I know it. In that knowing comes a great gift. I turn my heart again to my kind and understanding God and confess to Him that I need mercy. His answer swamps my heart with a too-good-to-be-true reality that leads to a crumbling of hopelessness and shame. My self-loathing collapses into His love. My self-condemnation melts into His arms that welcome and soothe. I have blown it. The blowing now has become the wind of the Holy Spirit. Ruah is here. His breath shepherds my heart into my Father's, and there mercy triumphs over judgment." I encourage you to read this book. God will use it to restore your soul, to bring water to your dry and weary soul, and to help you find rest in His strong arms. You will not feel condemned, but encouraged. I found hope in its pages.

Excellent, inspirational, challenging
Format: Kindle
Stasi doesn't just support her vision that God wants us live joyously with scripture, she acknowledges the challenges to that, the pain we experience in life, and then gives us practical advice for applying God's love through those times to become deeper, better, more loving individuals on the other side. I wish I had read this book before my Daddy was called home, but I guess I wouldn't have been the same person if I hadn't experienced that pain alone. Defiant Joy leads you beyond surface Christianity and challenges you to see God more closely.

Love this book!!
Format: Paperback
This book had me from go…the thought of choosing Joy as an act of defiance, not a denial of reality, resonates with me so deeply! I’m still reading, but I have already gifted two copies to dear friends!
