Description
The STEVAL-FCU001V1 is designed to support quadcopter drone designers. A complete sample firmware project allows the designer to begin flying small or medium sized quadcopters (with brushed or brushless DC motors) immediately and evaluate the performance of the IMU sensors under real flight conditions. The FCU can be controlled by a standard external remote controller (PWM input interface) or by a smartphone or tablet through the on-board Bluetooth low energy module (CE, FCC, ARIB, BQE certified). Magnetometer and pressure sensors are also embedded to support 3D navigation applications. SWD, I²C and USART connectors are available for firmware development and debugging, and to support additional external sensors or RF modules.
