good board to get feet wet with USB HID

[ieee488]

Which board would you recommend for getting "my feet wet" so to speak with USB HID ?

I purchased a Teensy LC ( www.pjrc.com) and have uploaded their USB Raw HID to it using the Arduino IDE.
It works although the device shows up twice in Windows 10 Device Manager.   


My goal is not a keyboard or a mouse, but for the board to send packets of information every 100 ms or so.

I would suggest any board with good support from the vendor and/or the community and an architecture and programming language you're familiar with.

Microchip is one of a number of vendors.

Microchip's website is bit disorganized for my taste.
Is there a low-priced evaluation kit you can recommend from them?

I am doing this as a learning exercise, so I don't want to spend much money.

Thanks.

Do you need to buy an eval board? The hardware is dead simple, why not just use plugin breadboard. A 18F25K50 doesn't even need a crystal!

So, you don't believe that it is unnecessary to buy their PICDEM FA USB Demo Board : https://www.microchip.com/DevelopmentTools/ProductDetails/PartNO/DM163025-1 ?
It is a bit pricey for me.

If I just buy the 18F25K50, don't I need to buy a USB breakout board so I can connect up to my PC ?

I was hoping for a $20 kit.

I purchased the Teensy LC and have it in my possession.
I will work with it some more.

Thanks.

Right, you said that! I think it's a good choice. Good luck with it.

I've implemented a lot of HID devices using the Teensy 2.0 (ATMega32u4, 8 bit AVR).
For something with Full Speed USB 2.0 the throughput is plenty.
Ok, this device is getting long in the tooth, but they're still selling them.

If I wanted High Speed USB 2.0 I'd go to the newer Teensy 4.0 (iMXRT1062, 600 MHz Cortex-M).
But that's a lot more complicated and a lot more power consumption.
Ok, if you are using the manufacturer's libraries it's not any more complicated.

Realistically, your Teensy LC is a fine choice.
Still, sending an HID report 10 times a second makes me want to grab the simplest device.
