# 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
|
|
|
|
