Bigger relais board
Would UniPi consider building a b bigger relays board?
If you would use these small 8A relays (1x NO €0.77), you could fit about 32 relays on one extension board the size of a UniPi board holder.
I think that most people that need many relays, only need 1x NO relay to use for steering valves or DIN rail relays and so on.
@Havor Is 56 relays + 4DO enough? https://www.unipi.technology/products/unipi-neuron-l403-40?categoryId=2&categorySlug=unipi-neuron
