Teensy 4.0: Flight Data Logger

Thu, 24 Sep 2026 00:30:00 -0400

Introduction

The Teensy 4.0 microcontroller is a low-cost, high-performance, and compact board. Carbon Aeronautics took advantage of these capabilities and adapted both its open-source code and PCB frame to use the Teensy 4.0 as the flight controller for a quadcopter. The board provides high processing power through its 600 MHz processor, along with the necessary peripherals and pins to connect the onboard sensors and devices (e.g., IMU, barometer, and ESCs). The flight controller can control the quadcopter at a loop rate of 250 Hz, demonstrating how capable this small board can be.

Introduction

With a personal goal of developing a deep understanding of quadcopter dynamics, I built my own quadcopter based on the open-source Carbon Aeronautics drone. This required purchasing parts online, making modifications, and assembling the whole quadcopter from the ground up until flight testing. Even though it may sound like a straightforward path from assembly to testing, I spent months stuck trying to make it fly due to both hardware and software issues. Little by little, the fun turned into frustration.
