From the project
DroneMagNav 2.0 - survey-fluxgate magnetic-anomaly navigation board for drones (IGRF-14 + EMAG2v3 continued to flight altitude)
GNSS-denied positioning from the Earth's crustal magnetic field, measured with a survey-grade three-axis fluxgate (no magnetometer on the board), plus the phone-operated great-circle route planner from v1.
J2 (JST-GH 10): 1 +12 V · 2 −12 V · 3 sensor power GND · 4/5 X out/return · 6/7 Y · 8/9 Z · 10 cable shield. Make the cable to your sensor's connector pinout (check the sensor manual); keep the sensor ≥ 0.5 m from motors.

DroneMagNav2.0: common questions
What microcontroller does the DroneMagNav2.0 use?
The DroneMagNav2.0 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.
How big is the DroneMagNav2.0 PCB?
The DroneMagNav2.0 measures 128 × 84 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the DroneMagNav2.0?
218 components, from 66 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the DroneMagNav2.0 design files?
From the ajisrawi/DroneMagNav2.0 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the DroneMagNav2.0 design in my own project?
