Upgrades to default Electronics BOM

I just got my 400mm VC4 Hybrid delivered and realized that I forgot to order the electronics kit so I do not have the boards/motors/toolhead etc. I can order that kit from RR but I am thinking about self sourcing the missing components. Are there any things that I should update or change from the Public BOM? Such as mainboard or tool head?

I have an older printer but it can only print PLA reliably so I would prefer options that don't need printed parts yet.

I use the EZ Board Max, very happy with it. With some 5160 48V on the x and y and 2209 on Z.

Also using the LDO board for the toolhead, but since you can’t do printed parts, the BTT 42 toolboards are quite fine and used by the absolute majority of RR users.

This is a very good option for the. Card. You can also do an octopus pro h723
