Flatsat 1 is a hardware-based training platform designed to be vulnerable — on purpose. Flatsat 1 is designed to help you learn and prototype radio systems safely and legally while gaining real-world skills in RF communication, signal analysis, and protocol fuzzing. 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. What You Can Do With Flatsat 1: Hands-on Learning – Use Flatsat 1 as the hardware companion to the PwnSat course from Electronic Cats, 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. Flatsat 1 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.Flatsat 1does not use sensitive or restricted space communication bands like X-band, Ka-band, or S-band. This ensures that Flatsat 1 does not interfere with any production space systems, licensed satellites, or critical ground infrastructure. Onboard Components:• RP2040 – Powerful MCU for comms and simulation.• BME280 – Environmental sensor for telemetry testing.• 2 x SX1262 – LoRa radios for realistic space-ground communication scenarios.• Open Documentation – Github Wiki with Getting Started.• LIS2DH – 3-axis accelerometer for sensor data emulation and tampering challenges.• OpenHardware – Schematics and Firmware. Train like a pro, without breaking the rules.
