SoftRF LoRa module

This module is designed to be pin-to-pin compatible with Nordic NRF905-based one.
Physical dimensions are very close.

Pros:

• better link budget ;
• very flexible RF chip settings allow implementation for variety of radio protocols, such as (FSK modulated):
  • "Legacy" (FLARM AIR V6) ;
  • P3I (PilotAware) ;
  • OGNTP (OGN tracker)
• when Semtech's proprietary LoRa modulation is in use, operating range of the SoftRF is increasing up to 2-4 times under same Tx power level.
  One known good implementation of the LoRa modulation for aviation proximity awareness is:
  • FANET protocol (Skytraxx)

PCB manufacturing

You can order the PCB direct from manufacturer:

It should typically cost you around 3-4 USD for minimum 4 pcs of PCB with basic international shipping included in.

Expect to wait:

• 1 week for panelization
• 2 weeks for fabrication
• 1-2 weeks for delivery to your location
