April Fools’ Day may have passed, but we really had to check the calendar on this hack. [Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno.

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

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...

The Arduino UNO R4 will be available in two versions, the ‘WiFi’ with an ESP32-S3 module, and the ‘Minima’. The R4 feels more like an update of the Arduino Zero, which, with its 32-bit ARM Cortex-M0 ...

Two versions of the new 32-bit Arduino UNO board will be offered: UNO R4 WiFi and UNO R4 Minima with the only difference being the former getting an ESP32-S3 module for wireless connectivity. Arduino ...

Arduino UNO R4 Minima (store / docs) - base version. Arduino UNO R4 WiFi ( store / docs ) - version with a Wi-Fi/Bluetooth module (ESP32) and a 12x8 LED matrix. This major change will introduce many ...

This leap forward starts with a new processor by Renesas, a global leader in microcontrollers, analog, power and SoC products. While over 10 million users have enjoyed playing and working with Arduino ...

The official Arduino team has this week revealed more details about the new Arduino UNO R4 development Board which will be officially launching in a few months time during May 2023. The ...

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

The Uno R3, with its 8-bit ATmega328P processor, has been a long-time favorite. But now, the Uno R4 is here to give a boost to your projects. Featuring a 48-MHz, 32-bit Cortex-M4 processor, abundant ...
