# Board - DALRCF722DUAL
|
|
|
|
The DALRCF722DUAL described here:
|
|
|
|
This board use the STM32F722RET6 microcontroller and have the following features:
|
|
* High-performance and DSP with FPU, ARM Cortex-M7 MCU with 512 Kbytes Flash
|
|
* 216 MHz CPU,462 DMIPS/2.14 DMIPS/MHz (Dhrystone 2.1) and DSP instructions, Art Accelerator, L1 cache, SDRAM
|
|
* DUAL gyro MPU6000 and ICM20602,could choose mpu6000,more stable and smooth.Or choose ICM20602,higher rate(32K/32K).Choose on CLI mode,experience different feature gyro on same board
|
|
* OSD on board
|
|
* The 16M byte SPI flash on board for data logging
|
|
* USB VCP and boot select button on board(for DFU)
|
|
* Stable voltage regulation,DUAL BEC 5v/2.5A and 10v/2A for VTX/camera etc.And could select 5v/10v with pad
|
|
* Serial LED interface(LED_STRIP)
|
|
* VBAT/CURR/RSSI sensors input
|
|
* Suppose IRC Tramp/smart audio/FPV Camera Control/FPORT/telemetry
|
|
* Supports SBus(built-in inverters), Spektrum1024/2048, PPM
|
|
* Supports I2C device extend(baro/compass/OLED etc)(socket)
|
|
* Supports GPS (socket)
|
|
|
