What exact does the term "Native USB support" mean ?

Post by Jerryy »

Hi:
I have purchased a number of Trinket M0 controller to experiment with. However I have never understood what
is meant in the description of the controller "that Native USB is supported". What exactly does this mean?

Thanks

That means the USB support is built into the processor chip. So they can emulate a USB serial port, mouse, keyboard etc.

Other processor chips - such as the Atmega328 used in the Arduino UNO cannot talk directly via USB. They need an extra chip do the TTL/Serial to USB conversion. This limits them those boards to just emulating a serial port. They cannot emulate other USB devices.
