Hello, I'm Electronics Engineer with experience making boars with Altium Designer. I worked on several IoT projects for Wifi, Bluetooth and GSM.
First i will need a document with the complete requirement to support the project scope. This need to include all details that need to be implemented.
This is the project plan:
1.- Make a small prototype with the principal hardware functionalities.
2.- Make the firmware to test the prototype. This is the idea to make the prototype first. Also this step can be made at the same time of (1).
3.- After the approbation of the firmware then i can make the PCB design to put in production.
4.- The end product is ready to use.
I work with project management tools that help to the client follow the progress with milestones, task, documentation, etc.
The organization help to make successfully projects.
The cost for prototyping and the project in general need to be discussed before start the project.
All specific details need to be shared in chat.
Regards.
