Hi
I'm still leaning keyboard PCB design. I've completed 1 macropad PCB project with a ATMEGA32U4-AU and it worked great - manufactured by PCBWay.
It already has a bootloader on, and you can load a QMK build when you hit the reset switch. USB just worked.
My next project I want to have manufactured by JLCPCB - however their ATMEGA32U4-AU are permanently out of stock. They do have a pile of ATMEGA32u4-MUR however...
In my design, can I just just swap out the -AU for the -MUR?
Is it just the package which is different?
Will it have the same bootloader? (DFU I believe)
Thanks
