Hi, from the website below, the massage I got is we can only get daughter board back from the project and we need to design our own carrier board, is that true or not? https://github.com/efabless/caravel_board/blob/main/docs/Caravel_Board_Specs%20_clean.pdf

No. Every designer will get back a handful of daughterboards and one caravel development board. For MPW-two (and probably through at least MPW-six) we are also giving each designer an STMicro Nucleo development board that fits under the Caravel development board (largely because it is being used to run software that works around several errors in the early chip designs, but it can also be used as a micropython development platform for chip testing).

@Tim Edwards Thank you for you reply, so my understanding is after we submit the efabless project, what we can get back is the chip we design and the caravel board right? So, my another problem is how to select the pcb board, they are have different type? and do we need to design the pcb board to cater for our chip design?

You get chips that are already soldered down to daughterboards, and the daughterboard clips into the caravel development board (one day we may replace the flexi-pins with a real socket, if we can find one that's cheap enough; test sockets tend to be expensive). You do not need to design a PCB unless you have special needs such as coax connectors or something else that isn't provided on our development board.

Along those lines, so all components that each of the boards need will already be soldered onto the boards when we get them? We don't have to purchase any of the components ourselves or solder any of them?
