Board - DALRCF405

The DALRCF405 described here: http://www.dalrcmodel.com/DALRC/plus/view.php?aid=184

This board use the STM32F405RGT6 microcontroller and have the following features:

  • 1024K bytes of flash memory,192K bytes RAM,168 MHz CPU/210 DMIPS

  • The 16M byte SPI flash for data logging

  • USB VCP and boot select button on board(for DFU)

  • Stable voltage regulation,9V/2A 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
