Hi, I was looking through this file given in the link: https://github.com/efabless/caravel_board/blob/main/docs/caravel_datasheet.pdf It seems there are 4 onboard regulators, but in the board schematic, there are 2 regulators (https://github.com/efabless/caravel_board/blob/main/hardware/caravel_pcb_v3_FTDI/caravel_pcb_v3_FTDI.pdf). So, there are two extra regulators in the Caravel datasheet. How can I find the information on them? Thanks

There are only the two regulators. The board has header pins so that the same regulators can be connected to either or both voltage domains, or else the header pins can be connected to a different external voltage supply.

Thanks for your reply.
