The pin position of Arduino mege2560 / due is not standard. I need to use the perfboard in the project and connect the DUE to it. This project is mainly to do a sampling circuit, the running speed of the whole circuit is between 10-20mhz, and the target signal to be collected is not less than 1MHz. A lot of underlying code is used in the programming process, and the whole circuit is similar to FPGA in operation, so the interference and delay become unacceptable. It seems that jumpers and DuPont wires are not the best choice. Besides being weak, they also introduce additional parasitic parameters and unexpected interference. I am not familiar with the use of drawing software and need to learn again, so it will cost a lot of time and money to draw PCB by myself. The hole spacing of the plate is 2.54mm. What should I do?
