Farnell has expanded its range of the iconic UNO family by introducing two new Arduino UNO R4 boards, now available for customers.
The Arduino UNO R4 is offered in two variations: the UNO R4 Minima and UNO R4 Wi-Fi. These versions bring exceptional performance and novel opportunities for makers, catering to both beginners and experienced developers. This advancement proves to be a cost-effective investment across all skill levels.
Leveraging the UNO family’s advanced features, the UNO R4 introduces a 32-bit architecture with an array of fresh capabilities for makers. Powered by the Renesas RA4M1 32-bit Cortex-M4 processor, the UNO R4 significantly enhances processing power, memory, and overall functionality. Importantly, these enhancements retain full backward compatibility, ensuring seamless compatibility with existing shields and accessories.
The UNO R4 Minima version provides high-end, powerful, and affordable technology for designers who want the power and speed of the latest microcontroller but have no need for additional features. Onboard SWD pins provide a simple way to connect third-party debugging probes that further ensure reliable system operation.
The UNO R4 Wi-Fi features an Espressif ESP32-S3-mini co-processor and offers Wi-Fi and Bluetooth connectivity, providing robust internet accessibility for IoT projects.
Key features common to the new Arduino UNO R4 models include:
- The Renesas RA4M1 (Arm Cortex-M4) processor running at 48MHz, providing a 3x performance increase over the UNO R3.
- SRAM upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.
- 12-bit analogue DAC
- On board OP Amp
- USB-C port
- Maximum power supply voltage of 24V with enhanced thermal design.
- CAN bus and an SPI port, enabling users to reduce wiring and perform parallel tasks by connecting multiple shields.
- HID device to emulate a mouse or keyboard
In addition to above, the UNO R4 Wi-Fi also includes:
- Low energy Bluetooth/Wi-Fi
- A fully addressable 12×8 LED matrix
- Qwic 12C connector for external I2C connectivity
- RTC with support for a buffer battery
- Runtime errors diagnostics
Romain Soreau, Head of Single Board Computing at Farnell, said: “Regardless of where you are on the development scale, from beginner to highly experienced professional, the new UNO R4 board provides makers and designers with a substantial increase in performance and, as a result, the power to convert new application possibilities into realities.”
Keith Jackson, Arduino Marketing, said: “Expanding our available portfolio with Farnell greatly extends our product availability to the right people, and makes it available to them at the right time. Our association continues to go from strength to strength to the ultimate benefit of designers and developers worldwide.”
Arduino is an open-source electronics platform based on easy-to-use hardware and software.
