The question is just as above: The Arduino Leonardo has been discontinued and I would like to know if there is any other board in the Arduino family that allows the keyboard and mouse to be directly controlled over serial? Thanks!
If you can no longer buy an original then why not get a clone?
There are many forms of the Leonardo. Leonardo, Micro, Sparkfun Pro Micro, DF Robot Beetle and CJMCU Beetle. These are all Leonardos and can be programmed as a Leonardo. The only differences are the physical size of the board and how many pins are broken out to the header pins. Just look for any board with an ATmega32U4 chip and call it a Leonardo.
