Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

One of the most significant differences between the classic Rev3 and Uno's more recent iteration, the R4 WiFi, is the microcontroller. This component is the brain of the board and is what gives ...

LUGANO, Switzerland--(BUSINESS WIRE)--Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant revision ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

32-bit Cortex-M4 Arduino has revised its UNO board and promised "a long-awaited update on performance and possibilities." The Arduino UNO R4 keeps the UNO family’s standard form factor ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

An UNO Shield that stacks onto Arduino boards (or Arduino-like boards such as Mbed) and provides an SPI interface to data packets that are sent or received using the EtherCAT protocol.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.
