Rocket Staging Separation Sequencer Kit with Arduino Mega + BMP280
Programmable Multi‑Stage Rocket Separation Sequencer Kit with Arduino Mega and Dual BMP280 Altimeters
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Fire stage-separation relays exactly when altitude crosses programmable thresholds, with a fully independent abort sequence if trajectory deviates beyond safe limits. Designed for rocketry teams, aerospace research groups, and serious amateurs who need a reliable, flown-proven electronics stack without spending weeks tracking down part numbers.
What You'll Build
A compact flight sequencer that reads altitude from two BMP280 sensors, monitors orientation via MPU6050, logs all data to microSD, and triggers any high-current pyro or solenoid relay at the exact meter you set. You’ll walk away with a self-contained unit in an enclosure, ready to mount on an airframe and test in the field.
What You'll Learn
- Dual redundant barometric altitude sensing with BMP280 and calibration against DS3231-timestamped logs
- Event-driven relay sequencing with Arduino Mega — defining stage‑1, stage‑2, and abort thresholds in code
- Failsafe abort logic that monitors MPU6050 pitch/roll and triggers all relays safe if boundaries are breached
- Assembling a rugged prototype on PCB board, including reverse‑current diode protection and reliable LiPo power regulation

Who This Kit Is For
Aerospace engineering students building a CanSat or sounding rocket project, teams preparing for Spaceport America Cup or university rocketry competitions, and hobbyists who have moved beyond single-stage flights and need a fully controllable staging solution. If you’re at IIT, NIT, VIT, or BITS Pilani rocketry clubs, this kit aligns directly with your competition electronics requirements.
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 inside the box and the AI companion provides step‑by‑step debugging. If you still need help, send a photo via WhatsApp and we’ll review your setup the same day.
How do I set custom altitude thresholds for stage separation and abort?
The pre‑loaded example sketch includes clearly marked variables for stage‑1 altitude, stage‑2 altitude, and the pitch/roll limits that trigger abort. You edit these values in the Arduino IDE before uploading; the AI guide explains every line.
Can I log actual flight data and use it for post‑flight analysis?
Yes, the microSD module timestamps readings from both BMP280s, MPU6050 attitude data, and relay state changes using the DS3231 RTC. CSV files are ready to import into MATLAB or Excel.
Is the relay module powerful enough for commercial pyrotechnic charges?
The 8‑channel relay can switch up to 10A per channel. If your deployment charges draw more, use the relays to trigger external high‑current MOSFETs — the AI companion shows you how to wire that safely with the included diodes.
Multi-stage relay sequencer fires stage separation relays at programmed altitude events with abort logic.
