The Crazyflie 1.0 is an open flying development platform. It is a versatile platform that includes a powerful Cortex-M4 MCU, 2.4GHz low latency radio and bluetooth low energy. It also has an expansion port which allows to easily add extra hardware.
HADES FCS is an open-source flight control system for unmanned aerial vehicles (UAVs) designed completely from scratch. This includes the hardware (custom flight-control PCBs), STM32 firmware (using FreeRTOS), Kalman filtering for state estimation, control algorithms, base station, communication protocol, flight simulator, signal processing, and much, much more.
TFGPS01 is a GNSS receiver designed for UAVs. The module has improved RF noise immunity and supports multiple navigation systems. Therefore the module is capable of receiving GPS, GLONASS, Galileo, and BeiDou navigation signals. It is designed primarily for use on small drones. The TFGPS can also function as a standalone UART GPS or as a USB GPS receiver.
The module has several features for UAVs. For example, it has a pass-through I2C port, payload interface, integrated beeper and safety LED or integrated connector for an external safety switch, and safety LED.
TFSLOT is Low speed airspeed sensor for UAVs. The device is equipped with electronics, which contains the required differential pressure sensor and an IMU unit. The sensor can be used as an external compass for the autopilot and it can improve the estimation of orientation in space. Accelerometer data, on the other hand, can be used to check vibrations. In contrast to classical Pitot tube, the TFSLOT design is perfect choice for low airspeed measurement.
