This is version 1.0 of software for EPS board.
As the release artifact, four .hex files are provided to flash AVR microcontrollers on EPS board.
For each microcontroller, there are two versions provided: with logs enabled and disabled, as per build system definition variable (LOG_LEVEL). Flight version is one with disabled logs.
EEPROM is identical for both microcontrollers and logging levels, therefore only one file is provided.
