Newark, a division of Avnet Inc., is carrying two new Arduino Uno R4 single board computers (SBCs) adding to its portfolio of programming boards for engineers and makers.
The two versions added to Newark’s portfolio include the Uno R4 Minima and Uno R4 Wi-Fi. Newark said both offer new possibilities for beginners and experienced developers to develop internet of things (IoT) projects.
The Uno R4 is powered by the Renesas RA4M1 320 bit Cortex-M4 processor giving the board a boost in processing power, memory and functionality. The boards are fully backwards compatible with other boards and work with existing shields and accessories.
Originally released in June, the Uno R4 Minima is designed for engineers that need the performance of the latest microcontroller but no need for additional features. The Uno R4 Wi-Fi features an Espreessif ESP32-S3-mini co-processor and offers both Wi-Fi and Bluetooth connectivity.
Other features on both boards include:
- 3 times performance increase over the Uno R3
- 32 kB of SRAM
- 256 kB of flash memory
- 12-bit analogue DAC
- On board OP Amp
- USB-C port
- Maximum power supply voltage of 24 V
- CAN bus and an SPI port
- AHID device to emulate a mouse or keyboard
Additional features on the Uno R4 Wi-Fi includes:
- Low energy Bluetooth/Wi-Fi
- A fully addressable 12x8 LED matrix
- Qwic 12C connector for external I2C connectivity
- RTC with support for a buffer battery
- Runtime errors diagnostics
