Dual-Deployment Rocket Flight Computer Kit with Arduino Nano, BMP280 & MPU6050

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

You're about to build a miniature mission computer for model rockets - a device that senses launch via a sharp drop in barometric pressure and a spike in acceleration, tracks the rocket's ride to apogee, and then fires deployment relays at two critical moments: first at apogee to release a drogue parachute, then again at 300 meters to deploy the main parachute. Every pressure reading, acceleration vector, and temperature point gets timestamped and stored on a microSD card, giving you a complete flight profile to analyze afterwards. This kit is purpose-built for the rigour of rocketry simulation, not just bench-top tinkering.

What You'll Build

By the end of this 6-to-8-hour build, you'll have a fully calibrated rocket flight computer and data logger. Mount it inside your rocket's avionics bay with a LiPo battery, and the system will autonomously detect launch, log flight data at 10 Hz, and actuate two 5V relays for sequential parachute deployment - all without any ground-to-rocket communication. The timestamped SD card file becomes your black box: ready for analysis of altitude, vertical speed, and ejection timing.

What You'll Learn

• Sensor fusion: combine BMP280 pressure data with MPU6050 accelerometer readings to reliably separate launch, coast, and descent phases
• Dual deployment logic: program relay triggers at apogee and at a pre-set altitude like 300 meters, using barometric data and a decision algorithm
• MicroSD data logging with real-time clock: write structured flight logs with DS3231 RTC timestamps and buffer management for high-speed data
• Power management for flight: build a 3.7V LiPo battery circuit with TP4056 charging and noise filtering from 100nF capacitors

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you're a B.Tech ECE, EEE, or Aerospace engineering student looking to prototype avionics for a campus rocketry competition, this kit collapses weeks of sourcing and debugging into a single build weekend. It's also ideal for participants in Smart India Hackathon (hardware edition), IIT/NIT/VIT rocketry club members, and serious model rocket builders who want to graduate from single-event recovery to two-stage parachute control. The wiring is advanced - you'll solder on prototype boards, not a breadboard - but every connection is documented in the AI companion.

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.

Choose your assembly option:

• Soldering Kit - 25W soldering iron, 60/40 solder wire, flux, and small perfboard for permanent assembly.
• Breadboard Combo - 800-point full-size breadboard with 65-piece jumper wire pack for solderless prototyping.
