STEVAL-FCU001V1: Flight Controller Unit Evaluation Board for Small Drones


The STEVAL-FCU001V1 is designed to support quadcopter drone designers.

A complete sample FW project allows the designer to begin flying small and medium size 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 Bluetooth low energy module present on board (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 FW development and debugging, and to support additional external sensors or RF modules.
