The terminal blocks on the MOSFET Driver board have latches that need to be pressed in order to properly insert the cables from a load, such as a motor or LED.
With your fingernail or a small flathead screwdriver, gently press down on the latch of the terminal block. With the latch pressed down, insert the wire from the load.
The tabs can break if too much force is applied
After inserting the wires they'll be securely plugged into the terminal blocks. If you pull on the wires, they should not move.
