      Z motors need more power. I have a total of 4 Z motors a 1800 mA. Officially, the board only supports 2400 mA. I connected them to the 2 slots on the board as intended and then wired them to 2 points each. I have the feeling that the 1.8 amps don't get through to the motors, but less. Is there a possibility, e.g. a load switch or something similar so that the motors can be sufficiently supplied.

        @axiom how have you split the z motors? In serials or parallel? Series gives full current and parallel half's the current to the motors

          @jay_s_uk Thanks for the tip, yes I connected them in parallel....do I have to solder them for a serial circuit, or do you have a link/tip where I can order such turnouts ready-made. In my search I only found parallel switches
