FYI: Just got a notice from Digikey about this new offering from MC
It has a M4808 + wifi and provides usb charging of lipo battery (not included)
MC part # AC164160
DK part # AC164160-ND price $29.87 and shows 191 in stock
Looks like a fun way to learn about the new AVR+0 chips
No programmer required, simple USB file drag and drop programming, also has console access via usb com port.
