I want to connect a Raspberry Pi to an 8-relay board, such as this one.
Together with ground and power this amounts to ten wires. One option to connect the two is by using female to female jumper cables, such as these.
However, this will result in a messy and delicate connection. For example, if one of the wires is accidentally pulled, there's the risk of reinserting it to a wrong pin. What's the professional way to connect the two boards with a cable?
