Which build target matches the schematics?

I'm building a setup based on this wiring schema.

Does this schema match the BOARD_DEFAULT or the BOARD_OLD build target?

BOARD_OLD. BOARD_DEFAULT is the PCB from Jye: https://github.com/AlessandroAU/Chorus32-ESP32LapTimer/blob/master/pcb/JyeSmith/PCBV2.2/Schematic-V2.2.png

Thanks! Is there a change log kind of thing to see how what changed in BOARD_DEFAULT? For instance if you want rewire things to match the new board.

What is the purpose of the two separate oled connections from vcc and gnd on the v2.2 PCB?

No just a different design for a PCB. Since most digital functions can be done by any pin, the assignment is quite arbitrary. If you already have wired everything, there is not much reason to change that.

I think it is to accommodate for different pinouts with those OLED modules

After some trail and error I found the v2.2 wiring easier to match with the ESP32 Devkit v1 that I'm using. With the first wiring I used you need to translate the pinout (and I failed to do that successfully).
