Arduino supported/Third Party Native USB micro processor - SOLVED

Using Arduino Microcontrollers
1

Hello, I'm looking for for micro processorthat are native USB that are support by arduino or Third party. Sense I can not get the Atmega32u4 which I normally get because of shortage / price jacking which leads me to finding another micro processor. My list is below.

ATMega32u4
SamD21
SamD51
Esp32
Pi pico
Stm32 (many)
Teensy (assorted NXP chips)
Pic32
TI tiva arm chips (via Energia)

This is my list so far. The atmega32u4 and the samD21 and SamD51 iI can not get unless I pay a higher price and or unavailable. Does the Community have more to add onto the list?

The ESP32 has native USB?

From What I have read it does have native USB. I have found this video https://www.youtube.com/watch?v=Eq6LS3RGOrI and forums stating native usb.

Thanks.

What are you trying to do with "native USB" that you were using 32u4 to do? How large of a quantity are you looking? If your reference is 32u4, then how much does your software rely on the exact hardware layer?

I was using webusb controlling some leds and other things. also reading out some tempersture sensor for logging.

Some pic32 (via mpide, I think)(nope. Now an installable board package)
TI tiva arm chips (via Energia)

Hey West, Thank you very much. I do have the SamD11. My problem with it is the lack of space only 16KB. that's what Prompted me to make this list to find another processor That has just a little more space and native usb.

I'm not familiar with the project software, what USB stack it's using. Your choices of the hardware may be limited by the software since it may be difficult to port the USB stack if it's written with too much hard-coding an no abstract layers. Take a look at your software, what ICs does it support? Pi Pico has stock but it's new and I have not knowledge of its USB stack.

Hello, all Yes there are limited of micro processors That are available because of teh chip shortage and I'm seeing now it is getting worse. The processors I normally get as of yesturday are now gone and it says anywhere from 46 to 84 weeks lead times. It is getting bad. Also another processor I was looking at maybe it is worse then the one I normally get. So for now the esp32 processor I'm going with for now thank you all for the help. and Thank you westfw I didn't know of a TI and the I never know some of the Pic32 has usb on them.
