Pin headers for wire wrap is long enough that you can have the female part on one side of teh board, and the pins reaching out on the other side of the PCB can mate with the female part on the next board.
Can you really manage to transfer all signals (while consume a number of pins for ground and supply voltage) in the 40 pins you have? Isn't it possible to get the memory on the same PCB as the processor? The connectors takes quite a big chunk of the PCB area unless you are using tiny SMD variants so you want features needing many signals to be on the same PCB as the processor. And because of noise, you want high-speed signals to stay on the PCB with the processor, so you can use EMI filters and series resistors to bandwidth-limit the signals between the boards. |
