RM3100 Isolated Coils
The industrial RM3100 sensor from PNI Sensor (USA) uses isolated coils for stable, repeatable magnetic readings.
Sensors
MagCore
SKU · AAD-MAGCORE · RM3100
A high-precision external compass built on the industrial RM3100 sensor (PNI Sensor, USA), connected over I²C. Isolated coils hold a clear heading even on high-current multirotors, and the compact module mounts away from motor and ESC interference for a clean magnetic reference.
Key Advantage
Industrial-grade RM3100 with isolated coils — high noise immunity and a clear heading even on multirotors where motors defeat other magnetometers.
Highlights
Core specs and the precision-sensing features that set MagCore apart.

13 nT Resolution
A fine 13 nT resolution delivers a precise, low-noise heading reference for accurate navigation.
EMI Immunity
High noise immunity holds a clear heading even on high-current multirotors where motors defeat other magnetometers.
Light 2 g Module
At just 2 g and 35 × 24 mm, MagCore adds negligible weight and footprint to any airframe.

Frequently Asked Questions
Why does MagCore use an RM3100 instead of a MEMS compass?
MagCore uses an industrial RM3100 (PNI Sensor, USA) over I²C with 13 nT resolution and isolated coils for high noise immunity — a clear heading even on high-current multirotors.
What is MagCore compatible with?
MagCore is built to run as one system on the AAD stack — it pairs with BattleCore FC7, MagCore CAN, NavCore DualBand and SensCore.
How does MagCore connect?
It connects via I²C; Mount X forward, Y right (or in 90° multiples); Change address for multiple compasses.
What's included in the box?
1× MagCore (I²C) module with RM3100 sensor.
Is MagCore NDAA-compliant and made in the USA?
Yes — MagCore is NDAA-compliant and made in the USA.
