Modular VRX monitor platform
Our design goals were:
- Base platform designed for rapid customization
- Utilize simple and robust commercial off the shelf electronics
- Utilize FDM small scale manufacturing for rapid design iterations and customization
- Integrate directional Antenna housing into screen cover
- Fit best-in-class TrueRC X1Air and/or X2Air directional Antennas
- Fit best-in-class TrueRC X1Air and/or X2Air directional Antennas
- Create multiple interchangeable VRX modules
