Magnetorquer Attitude Control Demo Kit with Arduino Mega + LED
Magnetorquer Attitude Control Kit: Simulate CubeSat Stabilization with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a three-axis magnetorquer system that actively corrects a simulated CubeSat’s orientation using real geomagnetic field data. This kit turns your bench into a spacecraft testbed, giving you hands-on experience with the same torque‑generation principles used by university satellite teams and ISRO’s student‑satellite programmes.
What You'll Build
A fully functional CubeSat attitude simulator that uses three orthogonal copper coils to create magnetic dipole moments. You will write control software that reads the 9‑axis IMU, computes the error from a commanded orientation, and drives each H‑bridge to produce precise torque. The system continuously displays attitude and current on the OLED, verifying your control loops in real time.
What You'll Learn
- Implementing B‑dot detumbling and PID‑based three‑axis attitude control
- Interfacing the ICM‑20948 IMU with Arduino for quaternion‑based orientation feedback
- Designing robust H‑bridge coil‑driver circuits with flyback diode protection
- Measuring magnetorquer torque output in‑situ using INA219 current sensors

Who This Kit Is For
Designed for B.Tech final‑year students in ECE, EEE, and aerospace engineering, especially those working on Smart India Hackathon satellite challenges or CubeSat projects at IITs, NITs, VIT, and BITS Pilani. It is also suitable for amateur satellite groups and ATL Tinkering Labs mentoring advanced‑class students through real spacecraft sub‑system design.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open the AI companion trained on this exact kit; it provides step‑by‑step debugging. You can also message us on WhatsApp from 10 AM to 7 PM IST for a personal reply.
Can I test attitude control without a real geomagnetic field?
The ICM‑20948 provides absolute orientation; you can inject synthetic field vectors via software to validate control algorithms indoors before outdoor testing.
Does the kit include a CubeSat structure?
No structure is included — you mount the coils orthogonally on the supplied PCB boards and frame them yourself, mimicking the CubeSat form factor.
Which programming environment is required?
You’ll use the Arduino IDE. All control libraries (IMU, INA219, PID) are provided in the companion code, ready to flash onto the Mega.
Three coil magnetorquers driven by H-bridges generate torque against Earth magnetic field for CubeSat attitude sim.
