LoRa Hub
Ready for prototype manufacturingLoRa Hub is a multi-channel LoRa concentrator and GNSS companion module designed for the NWIREDCORE Gateway Carrier Board.
What it is
LoRa Hub is a multi-channel LoRa concentrator and GNSS companion module for the NWIREDCORE CM4 / CM5 Gateway Carrier Board. It is designed to communicate with multiple LoRa sensor and device nodes while providing integrated GNSS functionality to the host system. It is a companion module, not a standalone device, and it always includes GNSS. It is a compact, castellated board intended to be mounted on a host board, with the layout driven by RF performance. Hardware design and the manufacturing package are complete; prototype manufacturing, bring-up and validation are still ahead. No prototypes have been built or tested yet.
Inside the RF section
The RF section is shielded in the assembled module. The open view is shown only to reveal the circuitry beneath the shield.
Board views
Top and bottom of the board (KiCad ray-traced renders). The RF shield is removed in the top view to show the component layout.

- SchematicCompleted
LoRa concentrator front end and GNSS receiver sections captured.
- PCB LayoutCompleted
Compact castellated layout complete, routed for RF performance.
- Manufacturing filesCompleted
Design and manufacturing files ready for factory ordering.
- Prototype manufacturingNext step
Next milestone: fabrication and assembly of the first modules.
- Bring-up and testingUpcoming
Power, LoRa communication, GNSS and basic interface checks on the first units.
- RF / GNSS validationUpcoming
Radio link and satellite positioning performance measured on hardware.
- Field testingUpcoming
- Revision if requiredFuture
Hardware design and the manufacturing package are complete; the next milestone is prototype fabrication and assembly. The current design is a multi-channel LoRa concentrator architecture — higher-level protocol software is not yet implemented or validated. Frequencies, output power, dimensions, certifications and production status are still to be confirmed through prototyping and are deliberately not listed yet.
