That is because the Arduino part frees the FleaFPGA Uno from the breadboard: you can easily program, control and interface ... Arduino shields (albeit only 3.3V ones), making it even more expandable.

But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.

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 ...

If you would like to join the Arduino UNO R4 early access program the team is now looking for authors and those that maintain a library or a popular open. Skip to main content; ...
