# - arduino:avr → Uno / Nano / Mega / etc. (built-in core, always needed)
|
|
# - ATTinyCore:avr@1.4.1 → ATtiny85 (Spence Konde's third-party core,
|
|
# drazzy.com index). Pinned to 1.4.1 because >=1.5.0 depends on
|
|
# micronucleus hosted at azduino.com (frequently unreachable). 1.4.1's
|
|
# micronucleus tool comes from github.com/digistump and still supports
|
|
# the FQBN clock options we ship (clock=16pll, etc.). We never invoke
|
|
# micronucleus — it is only required for USB upload, not compilation —
|
|
# but arduino-cli will not install a core whose tool deps cannot fetch.
