DIY Part List to build your own Stratux
Overview of a full parts/ component list to build your own Stratux Flarm with different components, such as AHRS, Pressure Sensor, FLARM out, etc
Basic Components for Stratux, to receive both, ADS-B and Flarm traffic:
- external GPS antenna (BL1 Stratux GPS)
- internal GPS antenna (BL1 Stratux GPS Module)
- Suction Cup Holder
- universal Suction Cup Holder
- ADS-B Bundle: Dual-Band NESDR Nano 2+ (recommended)
- ADS-B Bundle: Dual-Band NESDR Nano 2
- external optimized 868MHz FLARM antenna
- Raspberry PI 3B (recommended)
- Raspberry PI 4B
- Passive Heatsink for Raspberry PI 3/4
Cases for Stratux 2 (receive only):
- Case for Stratux, fits for AHRS, two Fans for optimal cooling (recommended)
- tiny Case for Stratux, fits for AHRS, but has only one Fan
Cases for Stratux 3 (receive and transmit):
- original 3D printed Stratux 3 case
- size optimized Stratux 3 case for T-Beam
- size optimized Stratux 3 case for T-Motion
AHRS and Pressure Sensors:
- PCB circuit board required to professionally mount below sensors to GPIO header
