Flight controller unit evaluation board for drones

The STEVAL-FCU001V1 board from ST is designed to support quadcopter drone designers with the latest solutions for motor control, sensors and and microcontroller.

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.

LSM6DSL – 3D accelerometer and 3D gyroscope

P3797D-Low-Power-6-Axis-MEMS-Modules-IMAGE

Two low-power 6-axis inertial modules introduced from STMicroelectronics, the LSM6DSL and LSM6DSM. Both they pack a 3-D digital accelerometer and a 3-D digital gyroscope in a miniature package. These modules consume 0.4 mA in combo normal mode and 0.65 mA in combo high-performance mode, cutting power consumption by as much as 50% over their current predecessors. The LSM6DSL has a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±245/±500/±1000/±2000 dps.
