Components
This suggestion addresses the availability of the assembled PCB.
Proposal
Work with manufacturers to offer off-the-shelf purchase of the PCB that is programmed and ready to be used. Create a user manual and application guide to enable end users to properly use the product.
Benefits
Off-the-shelf hardware availability will significantly increase adoption and use which will in turn grow the project and help it become more successful.
