Hello Sam,
Actually,we don't create custom board for customers. It's a hard work to develop, to certify and to manufacture. It is a very long process. What's we are offering today is only reference designs and quick evaluation sensor kits. NXP is a "chip maker", and not a "system creator". All the tools we're developing are to help the customer to quicky assess our devices and make easy prototyping. But we like to have feedback and ideas from customers for future kits and all inputs are welcome (but I can't commit).
If you need a custom board, you can do it by yourself, it exists a lot of free design tools and a lot of very cheap pcb manufacturer or you can ask a third party.
Thanks,
Anthony
