Arduino Uno R4 WiFi

Arduino Uno R4 WiFi

The Arduino UNO R4 WiFi merges the RA4M1 microprocessor from Renesas with the ESP32-S3 from Espressif, creating an all-in-one tool for makers with enhanced processing power and a diverse array of new peripherals. The UNO R4 WiFi gives makers access to a world of limitless creative possibilities because to its integrated Wi-Fi® and Bluetooth® capabilities. Additionally, this adaptable board has a simple built-in 12×8 LED matrix and a Qwiic connector, providing lots of room for creativity and invention. This powerful mix enables creators to bring their visions to life and take their ventures to new heights.

• Hardware compatibility with UNO form factor: For existing shields and projects, the UNO R4 WiFi’s identical form factor, pinout, and 5 V operating voltage to its predecessor, the UNO R3, provide a smooth transfer.
• Expanded memory and faster clock: With additional memory and a quicker clock speed, the UNO R4 WiFi enables more accurate computations and the simple management of challenging projects.
• Extra on-board peripherals: With the addition of various on-board peripherals like a 12-bit DAC, CAN BUS, and OP AMP, the UNO R4 WiFi offers increased functionality and design flexibility.
• Extended 24 V tolerance: With a larger input voltage range supported by the UNO R4 WiFi, motors, LED strips, and other actuators can be easily integrated utilizing a single power source.
• HID support: When linked to a computer through USB, the UNO R4 WiFi can emulate a mouse or keyboard, making it simple to send keystrokes and mouse movements.
• Wi-Fi® and Bluetooth®: The ESP32-S3 module, which is housed on the UNO R4 WiFi, enables builders to include wireless connectivity in their projects. Makers can remotely monitor and control their projects by using the Arduino IoT Cloud.
• Qwiic connector: The Qwiic I2C port on the UNO R4 WiFi enables simple connectivity to nodes within the vast Qwiic ecosystem. Additionally, adapter cables allow for compatibility with sensors and actuators using different connector types.
• Support for battery-powered RTC: Additional pins on the UNO R4 WiFi include a “OFF” pin to turn the board off and a “VRTC” pin to maintain power to the onboard real-time clock.
• LED matrix: A brilliant 12×8 red LED matrix built inside the UNO R4 WiFi makes it perfect for animation projects or graphing sensor data without the need for additional gear.
• Diagnostics for runtime errors: A runtime crash detection feature that also provides thorough justifications and hints regarding the specific code line responsible is built into the UNO R4 WiFi.
