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
