I picked up a couple of these Curiosity boards from Microchip for US $6 (on sale, regularly $10) https://www.microchip.com/developmenttools/ProductDetails/DM320115 .
The hardware user guide is here: https://ww1.microchip.com/downloads/en/DeviceDoc/ATmega4809-Curiosity-Nano-HW-UG-DS50002804A.pdf .
The schematic is here: https://ww1.microchip.com/downloads/en/DeviceDoc/ATmega4809_Curiosity_Nano_Schematics.pdf .
The ATMega4809 data sheet is here: **broken link removed** .
This morning, I was reading through the docs and looking online and so on, figuring that I would test out a board in MPLAB X IDE.
I came across an interesting Arduino core development project by Hans (MCUdude), MegaCoreX, that can use the board, GitHub page here: https://github.com/MCUdude/MegaCoreX .
Less than 10 minutes later, I was running Blink.ino at 20 mHz. The project is a work in progress, but I think it is impressive.
Thought some others might be interested.
