Board - FLYWOOF411
This board use the STM32F411CEU6 microcontroller and have the following features:
- The 16M byte SPI flash for data logging
- USB VCP and boot select button on board(for DFU)
- Stable voltage regulation,9V/1.5A DCDC BEC for VTX/camera etc.And could select 5v/9v with pad
- Serial LED interface(LED_STRIP)
- VBAT/CURR/RSSI sensors input
- Suppose IRC Tramp/smart audio/FPV Camera Control/FPORT/telemetry
- Supports SBus, Spektrum1024/2048, PPM. No external inverters required (built-in).
- Supports I2C device extend(baro/compass/OLED etc)
- Supports GPS
All uarts have pad on board
