Arduino on Microcontroller with usb?

Other Hardware 3rd Party Boards
1

Hi

I heard about some MC's that have built-in USB-Support.

Does anybody if there some around that can be programmed with arduino bootloader?

(And should be somthing in SOIC,PQFP,PLCC style be, because i have to hand-solder)

How about the 32u4?

It's used in the Leonardo and micro, so you can start development without making your own board for it.

Thank you! Its a very expensive chip though, but i might be order them from china :slight_smile:

Clones of the Arduino Micro can be had on ebay for like $4 (be sure to check listing carefully to make sure you're getting a 32u4-based board, (a Micro clone), not a '328p-based board with a usb-serial chip on it (a nano clone)

And there's the point.

If you are concerned about hand-soldering then you are clearly not talking about a (significant) commercial production run, don't even bother to attempt to re-invent the wheel.

Just buy the complete "Pro Micro" module from China, already assembled with all required components. If you feel the need to make a PCB to mount your custom components, that is not a problem - you just lay out the pin footprint of the Pro Micro on to that PCB and either socket it, or solder it in using the pin headers provided. You can even populate the board with SMD components under the module.

Thanks for that great idea! :slight_smile:

I use 32U4 for the builtin USB support as well as the fact that there is an extra hardware serial port which was needed for my application.
Designed a 'stand alone' arduino based on the 32U4 and uploaded the micro's bootloader.

Bought atmega32u4 for less than $4 from here :
