What is the best place to purchase raw ATMega328P chips w/o the bootloader?
Define "best".
Cheap and quick, bulk purchasing works
Is there any place to buy ATmega328p chips in bulk, bootloader or not? Last I looked, lead times were months to two years.
e.g. https://www.mouser.com/c/?q=atmega328p
Any that you get from China are more or less guaranteed to be counterfeit.
Yeah. "World-wide chip shortage."
ATmega4809s (as used on Nano Every), and a bunch of the new xTiny and AVR-Dx chips have better availability. (Supported in Arduino by Spence Konde's core.)
Indeed, Mouser has the ATmega4809 in stock, even the 40 pin PDIP.
Will take a look. Thanks.
I made some cute little PCBs for the DIP 4809. It puts all needed components (bypass caps, auto-reset cap, Serial and UPDI connectors, etc) in the blank spaces of a 40pin socket, and lets the pins extend far enough to fit in a protoboard. There's an SMT version and a TH version.
Also a Uno-WiFi format board with no WiFi, although it makes heavy use of cheap modules: GitHub - WestfW/ATmega4809-designs: A couple of PCB designs using the Microchip ATmega4809 microcontroller. More-or-less compatible with Arduino

Buy complete arduino clones and remove them!
