Teensy vs. Arduino Nano - I got both for different purposes.

Projects General Guidance

I am new to the subject of HID USB. Is Teensy better than Arduino Nano for USB HID interfaces?
What exactly keeps those FTDI USB chips from being accepted well by the (Windows) Operating System?
How do devices that use separate FTDI interface with Windows?

How do I choose between Interrupt transfer, Bulk transfer and Isochronous transfer if I use FDTI chips?

Thank you
Vladimir.

Teensy. Change a menu item in the Arduino IDE. Upload your sketch. Done.

An alternative that has similar functionality to the Teensy...

I was asking about the hardware differences...

OK. Hardware differences...

Thats a lot to read and I still don't understand what makes one a better HID device platform than the other.

I read all links. Still in few words,
tell me please, what makes a difference?

Thank you.

The teensy boards are better for hid devices because i have an arduino and i know that they don't work for USB HID. Some of the other arduino boards like the leonardo and the pro mini are capable of being used as HID devices but the nano isn't due to a different USB Programming chip. Go with the teensy for all HID uses.

Teensy (and Arduino Micro and Leonardo) use ATMEGA32u4, Nano (and most other Arduinos & clones) use ATMEGA328, along with either software or physical USB to serial conversion. The 32u4 does it all in-chip.

Whoops. I should look at the whole thread, not just the last posts! :fearful:
