# Model Rocket Flight Controller

A compact 2-layer flight controller PCB designed for model rocket applications.

## PCB Preview

## Overview

This project is a small form-factor flight controller designed for model rockets.

The main goal was to fit the required sensors, microcontroller, power and control

interfaces onto a compact 2-layer PCB.

The board is approximately **6 × 6 cm**, making it suitable for applications where

PCB space is limited.

## Main Components

- **ESP32-WROOM-32E** – Main microcontroller

- **BMI088** – 6-axis IMU with gyroscope and accelerometer

- **Bosch BMP388** – Barometric pressure sensor for altitude measurement

- **USB interface** – Dedicated USB connection for programming and controlling the ESP32

- **Buzzer** – Audible indication

- **Status LED** – Board status indication

- **Push buttons** – User input and control

- **Power and peripheral connectors**

## Design

The ESP32 is used as the main controller of the board. The BMI088 provides

acceleration and gyroscope data, while the BMP388 is used for pressure and

altitude-related measurements.

A dedicated USB interface is included for programming and direct communication

with the ESP32.

The PCB was designed with a focus on keeping the board compact while still

providing the required sensors, connectors and control interfaces.
