Are you sure? Please do the following to confirm:
The IDE should be at version 1.8.7
You will probably see this given in the IDE’s top window bar.
- In the IDE menu select:
File > Preferences
- In the Preferences window check the box for

OK at the bottom right of the Preferences window.
- Load the Arduoboy2 HelloWorld example sketch:
File > Examples > Arduboy2 > HelloWorld
If you compile the HelloWorld sketch, you should see output with the following version numbers:
Using library Arduboy2 at version 5.2.0 in folder: xxxxx
Using library EEPROM at version 2.0 in folder: xxxxx
Sketch uses 6992 bytes (24%) of program storage space. Maximum is 28672 bytes.
Global variables use 1216 bytes (47%) of dynamic memory, leaving 1344 bytes for local variables. Maximum is 2560 bytes.
As @filmote said, the 1AAA00 is a customised name or garbage set in the system EEPROM. You can change or clear this using the Arduboy2 library’s SetSystemEEPROM example sketch:
