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.

  • RoHS compliant

SD Card Sound Player

audio3

fasoft @ elektormagazine.com has a new project proposal about a SD Card Sound Player.

Searching for a powerful gong or acoustic notifier? The “Card Sound” consists of audio amplifier TDA7266 having 2x 7 W output, the AD converter CS4344, one STM32F401 and a slot for micro sd card. Objective is to play different sounds stored on an SD card. Current schematic has one TWI port for control. Amend other interfaces like RS-485, UART, SPI etc. is also possible.
