HiLetgo BadUsb Beetle Bad USB Microcontroller ATMEGA32U4 Development Board Virtual Keyboard for Arduino Leonardo R3 DC 5V 16MHz

Works perfectly fine you do need to install Arduino app for it to work but this is a great product highly recommend

I picked up the HiLetgo BadUSB Beetle mainly for small USB automation projects, and it works really well once you get it set up. It is super compact and easy to program through the Arduino IDE, recognized as an Arduino Micro, but you definitely need some basic experience with microcontrollers or HID scripts to use it properly. The board can emulate keyboard and mouse inputs, which is great for automation, but out of the box it may have a default payload loaded, so flashing your own code right away is a must. Build quality is decent for the price, though the USB connection feels a little loose, so you will want to secure it if you are using it long-term. Overall, it is a solid and affordable board for anyone comfortable with Arduino programming who wants a tiny, powerful HID device.

great product, very discreet and easy to use, 10/10

first time I plugged in was to a Windows machine, as another review mentioned this is stupid. it immediately ran cmd. the command prompt had no command history so maybe it's just what these things do as default, just open cmd. anyway that's sketchy to me. other than that it's easily recognized and programmed with Arduino IDE.for the price I don't think you can beat this, you can make it yourself but where do you get a nice case like this? if I knew how to diy this for cheaper or same price I would.kind of right going in and out of the USB port not the greatest fit.

Works great. Super cheap and does what its supposed to.

Product received was non-functional. Tested on multiple devices. You get what you pay for.

Bought this to create a "mouse jiggler". For that purpose, it works very well.

They are 1/2 of the price on aliexpress for the exact same item.
