Hi all. I am a preety stupid with electrical stuff, so want to ask help here.
So, I am trying to make hardware keyboard and mouse emulator. I want to make one teendy boart to be a mouse+keyboard device on one PC and another teensy board to be a reciver(using HID RAW device) on another PC(so, one PC will retrieve mouse movements and key press from PC and send them to another teensy board).
I need to connect one teensy to another, I guess serial connection will be okay, but they will have different power sources. How to properly connect them? Is it enough to connect teensys GND (e.g. one power source GND will be connected to another power source GND) and after that connect serial pins? Or I need some resistors or whatever on pins to avoid board damage when one board is powered and sending signals, and other board is off?
Thanks in advance
