Hi, If you mean this type of pump "https://s.click.aliexpress.com/e/_DC1usdz" they have water input and output ports. Just throw the inlet hose into the water tank "height difference should not be very large", and the output hose goes to the plants.
droplet has 5 outputs for pumps each capable of outputting "5V 400mA" so if you want to connect other pumps, pay attention pump's power consumption.

Thanks for the quick response!
When I go to your shop, I cant choose main board + expansion board?
Do you have this board in stock or?
