Pcb design and program with possible app

We are in search of a skilled team capable of designing, programming, and integrating a set of four PCBs from the ground up, ready for immediate use. Our project includes:

1. An RF controller,
2. A main receiver computer coupled with a transmitter for motors,
3. A BLDC motor controller capable of handling 400 amps, and
4. A GPS board.

The team must exhibit proficiency in:

- Programming,
- PCB design,
- Bluetooth technology,
- RF controllers,
- App development.

Included are the detailed circuit board requirements and two suggested microcontrollers for consideration, though we remain open to expert recommendations.

We seek partners who can bring substantial experience to the table, particularly those who have previously completed successful PCB design and development projects. If you do not have a portfolio of past projects that showcase your capabilities in these areas, we respectfully ask that you consider how your skills align with our needs before reaching out. We welcome proposals from both agencies and individuals, focusing solely on the expertise and value you bring to our project.
