While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...

That doesn’t mean the Arduino is limited to the capabilities of an ATMEGA328 chip. There are plenty of board variants available, with an entirely different set of features like different ...

2. Arduino Mega The Arduino Mega is a bigger version of the Uno board, packed with more pins for larger projects. This board features an ATmega2560 microcontroller, 54 digital input/output pins, 16 ...

The latest board, the Arduino Uno, runs on a 16 MHz Atmel ATmega328 micro and has 6 12-bits analog to digital converters, 14 digital I/O pins (6 of which will do hardware PWM) and has 32kb of Flash, ...

That link also contains listings of workshops using the Shrimp microcontroller. Since it appears just like an Arduino Uno you can do any of the hundreds of projects for that board.

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will ...
