· While extending the terminal, the original expansion board sockets are retained, which also allow users to stack other expansion boards on it.
· The expansion board extends the terminal post to the outside. Even if multiple expansion boards are stacked, you can still use these ports without being blocked by other boards.
· This kit can let your projects be free of breadboard wiring, making circuit construction easier and more reliable. The terminal uses screws to clamp the wire, to which wires can be directly screwed in.
