Arduino core using ATMega4809 and the Curiosity board

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: http://ww1.microchip.com/downloads/en/DeviceDoc/ATmega4809-Curiosity-Nano-HW-UG-DS50002804A.pdf .

The schematic is here: http://ww1.microchip.com/downloads/en/DeviceDoc/ATmega4809_Curiosity_Nano_Schematics.pdf .

The ATMega4809 data sheet is here: http://ww1.microchip.com/downloads/en/DeviceDoc/40002016A.pdf .

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.
