Rocket Staging Separation Sequencer Variant 7 Kit with Arduino Mega + BMP280
Program an Altitude-Staging Rocket Sequencer with Arduino Mega – Multi-Stage Separation & Abort Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Recreate the flight-qualified brains that command multi-stage rocket separations. Using dual BMP280 pressure sensors for redundant altitude sensing, this kit guides you through implementing a robust sequencing system that fires relays at precise altitude thresholds and triggers an abort if the vehicle tilts beyond limits. Perfect for university rocketry teams, prototype flight electronics developers, and advanced hobbyists designing reliable staging controllers.
What You'll Build
A self-contained, battery-powered flight sequencer that measures altitude from two independent barometers, commands up to eight separation relays, detects tilt via MPU6050 to abort staging if the rocket veers off course, and logs every event with an RTC timestamp to a MicroSD card. The unit is housed in a rugged enclosure, runs on a rechargeable LiPo cell with integrated charging, and displays real-time status on a 0.96-inch OLED.
What You'll Learn
- Implement dual-sensor altitude voting to increase flight-critical reliability
- Code non-blocking relay sequencing on Arduino Mega with hardware interrupts for abort logic
- Calculate tilt angle from MPU6050 accelerometer data and define a safe launch envelope
- Design a power-safe LiPo management circuit with TP4056 charging and reverse-polarity protection

Who This Kit Is For
This advanced kit targets final-year B.Tech ECE/EEE students developing proof-of-concept flight sequencers, members of university rocketry teams at IIT, NIT, VIT, and BITS Pilani, and participants in the Smart India Hackathon working on rocketry automation challenges. It is also ideal for embedded systems professionals prototyping multi-stage staging logic and for ATL tinkering labs mentoring advanced space-tech projects.
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?
The AI companion provides step-by-step debugging tailored to this sequencer; you can also contact our team on WhatsApp for direct assistance.
How do I customize altitude setpoints for my rocket?
Setpoints are stored on the MicroSD card as a plain-text config file. You can edit them directly via a PC or through the OLED menu using the included navigation logic.
What if the two barometric sensors give slightly different readings?
The firmware implements a weighted voting algorithm that rejects outliers. You can also calibrate both sensors against ground-level pressure through the setup menu.
Can I test relay firing without connecting pyrotechnics?
Yes, the kit supports a bench-test mode where relays can trigger LEDs or buzzers. The AI guide walks you through a complete dry-run sequence to verify logic before a real launch.
Multi-stage relay sequencer fires stage separation relays at programmed altitude events with abort logic.
