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

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.

Arduino intends to provide a public list of such libraries, with links to alternatives. To aid library developers in porting low-level code to the Renesas architecture, there is and early-adopter ...

Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant re ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.

1x SPI (D10-D13, ICSP header) 1x I 2 C (A4, A5, SDA, SCL) 1x CAN (D4, D5, needs external transceiver) USB 2.0 full-speed (able to simulate a mouse or keyboard to a host PC). Op-amp Capacitive touch ...

The Arduino UNO R4, featuring the Renesas RA4M1 (Arm Cortex-M4) running at 48MHz, boasts a 3x performance increase over the UNO R3. Additionally, SRAM has been upgraded from 2kB to 32kB, and flash ...
