🚀 Flatsat: The Hackable Spaceboard #

Flatsat is a hardware based training platform designed to be vulnerable — on purpose. It’s built for hackers, engineers, and space enthusiasts who want to dive deep into space-grade systems, learn cybersecurity concepts, and prototype their own payloads.

Flatsat is part of the larger PwnSat Project, a complete space cybersecurity training course and mission-based CTF challenge where you’ll learn to attack, defend, and reverse engineer space firmware.

🧩 What You Can Do With Flatsat #

• Hands-on Learning – Use Flatsat as the hardware companion to the PwnSat course, with structured lessons on binary exploitation, secure communication, reverse engineering, and space protocols.
• Hack Real Vulnerabilities – Explore and exploit firmware designed to simulate real-world satellite systems and vulnerabilities. It’s a safe playground for learning and discovery.
• Join the Mission CTF – Participate in space-themed capture-the-flag challenges that simulate real satellite operation scenarios. Your board becomes your spacecraft!
• Prototype Your Payloads – Use the onboard components to develop and test your own payload logic, radio communication, or telemetry systems before launching bigger projects.

🧪 Onboard Components #

• ESP32-S3 – Powerful MCU with Wi-Fi and Bluetooth for comms and simulation.
• SX1262 or RFM95 – LoRa radio for realistic space-ground communication scenarios.
• MPU6050 – 6-axis IMU for sensor data emulation and tampering challenges.
• BME280 – Environmental sensor for telemetry testing.

📡 Frequency Safety Notice #

Flatsat uses ISM (Industrial, Scientific, and Medical) band frequencies for all RF communication — typically 433 MHz or 915 MHz, depending on your region. These frequencies are internationally reserved for unlicensed, experimental, and educational use.

We do not use sensitive or restricted space communication bands like:

• ❌ X-band
• ❌ Ka-band
• ❌ S-band

This ensures that Flatsat does not interfere with any production space systems, licensed satellites, or critical ground infrastructure.

Flatsat is designed to help you learn and prototype radio systems safely and legally — all while gaining real-world skills in RF communication, signal analysis, and protocol fuzzing.

🔒 Train like a pro, without breaking the rules.

Nothing it’s done by itself LyndLabs make it possible #

LyndLabs is the hardware design partner behind the Flatsat project, working closely with firmware developers to bring educational and hackable space-tech to life. While the firmware powers the logic, LyndLabs provides the robust physical foundation — from schematic design to PCB layout — making sure every component supports hands-on cybersecurity learning. Together, this collaboration fuses hardware precision with low-level software to create a truly immersive and functional training platform.
