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.

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

The Board Overview Now, if we look at the Arduino Uno R4 WiFi development board, we can see that it comes with many hardware upgrades over its predecessor. Here is a part marking image of the Arduino ...

Waveshare R7FA4 Plus A Both the Waveshare R7FA4 Plus A and B boards are functionally equivalent to the Arduino UNO R4 Minima and WiFi boards, except for the additional support for 3.3V Arduino shields ...

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 ...

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 ...

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 ...
