I feel the SAMD11 is still very much underrated
You get the largest one for 0.63€ at Digikey!
A no china fake ARM M0 with crystal less USB, this should be all the rave right now and replace the damn ATTINY85. Also avail in easy to solder large pitch SOIC

And yes it has Arduino support: https://github.com/mattairtech/ArduinoCore-samd

Maybe">https://github.com/mattairte... @Adafruit wants to make an even lower cost trinket with it?

Though I think this is a special price atm, its normally 20-30 cent more expensive.

And to give you a better perspective.
This MCU can run with nothing but a 3V coin cell and give you native FullSpeed USB!
Yes decoupling cap makes it more stable but it runs just as (semi) robust as an ATtiny with a plain battery supply.
(for all those solder kit creators)

And its much easier to interact with without a bootloader, no stupid fuses to fiddle with, very capable programmers/debuggers are available for 1.5$!
No slow ass ArduinoISP BS anymore because you& #39;re too cheap for that 35$ programmer. https://www.aliexpress.com/item/32792513237.html">https://www.aliexpress.com/item/3279...

@MicrochipMakes maybe you should promote this little gem a bit more :)
A 32kb variant would also be great
