Perfecto para proyectos dónde se requiere poco espacio y algunas funciones sencillas

I'm using 5 of these in single lever, 3D printed train driving simulator controllers i've made. These program the same as an arduino leonardo, which means you can use them as a HID joystick or keyboard with no messing about. I use mine to read potentiometer and switch positions, and send keystrokes to a simulator that does not accept joystick inputs yet. This is where i needed a board that does the HID stuff, and also i didn't want a large board where i would only be using 1 or 2 of the inputs, and having 20 or so wasted inputs.

La compacité de cet arduino est impressionnante, tout en restant "humaine". La documentation est relativement difficile à trouver pour ce modèle spécifique. Le constructeur dit que c'est compatible 'Leonardo', mais on voit bien que ce n'est physiquement pas identique, qu'il n'y a pas le même nombre de connecteurs et il y a aussi des limitations en terme de broches qui gèrent les interruptions (et comme ce n'est pas clairement documenté, c'est difficile à confirmer / tester / utiliser). Sinon une simple connexion USB permet de commencer à s'amuser sur des montages simples. Petit "truc" pour le cas où cela vous arriverait: La perte de la communication série avec l'Arduino n'est pas toujours résolue en débranchant / rebranchant à l'USB. Dans ce cas, redémarrer le PC et ça fonctionne à nouveau (ça m'a fait le coup plusieurs fois).

Sehr guter, kompakter Arduino. Sonst wie gewohnt.

Made my smallest K3NG, using the Beetle as its heart. I only had to change which pins were input/output and nothing else in the code for the upload to take and work first shot. It doesn't have as much memory space as a full Arduino Nano, but the SDA and SCL pins are better marked, as are the VCC and GND pads. The pads are big, and easy to solder, overall even better than the old Digispark boards.
