## Overview

The DFROBOT-282 Beetle is the smallest Arduino-compatible microcontroller board, featuring an Atmega32u4 processor running at 16MHz, 10 digital pins, 5 analog pins, and 4 PWM pins. Its compact 120mm x 22mm form factor and Micro USB connectivity allow for direct programming and testing, making it ideal for space-constrained projects without compromising on versatility or ease of use.

## Description

The new generation" beetle" controller derives its core notion from minimalism without compromising functionality. It comes with atmel atmega32u4 @16MHz clock time and has expanded amounts of interfaces: 10 digital pins, 5 analog pins and 4 PWM pins. To further make it user-friendly, it is compatible with Micro USB so that direct programming and testing is no longer a headache. Select" arduino leonardo (tools > board > arduino leonardo in arduino ide), the atmega32u4 comes pre-burned with a bootloader that allows you to upload any new Code that is applicable to arduino leonardo.

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

## Features

- Micro usb: 1
- 20Mm x 22 mm compact size

*by J***C on 6 May 2024*

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).
