I picked up a few of these nameless #Arduino-ish boards from #Electrodragon. They have the ATMega4808 on them, similar to an Arduino "Every" which has the '4809.
At $4.50 ea it's a good deal.
Programming is a bit different with the #MegaCoreX library involved, and wiring up a Nano as a programmer.
Will tack on some threaded cmts about how it goes. A bit cryptic so far, but thankfully not much cash nor time invested yet.
I've had some luck with that #ATMega4808 board as far as getting an #ArduinoNano wired up as programmer and using the #JTAG2UPDI code to push a 4808-friendly bootloader onto the device.
A problem though has brought me back into the nuances of the #CH340 serial chip world, which I had hoped I was done with yrs ago.
Seems maybe older MacOS versions have probs with CH340K vs G vs other variants.
I'm still on BigSur though, so perhaps this is reason to increment up to Ventura.
Sadly updating to Ventura didn't solve my #CH340 problem. This ATmega4808 board with the CH340K is still not visible beyond the system_profiler view (doesn't show up in /dev).
Maybe in Sonoma, but I'm not going that far.
Next approach is to install the latest Chinese device driver for it, but on an older machine that doesn't use the Apple driver: "DriverKit-AppleUSBCHCOM" which seems to be the culprit.
