   6 This board use the STM32F722RET6 microcontroller and have the following features:
   7 * High-performance and DSP with FPU, ARM Cortex-M7 MCU with 512 Kbytes Flash
   8 * 216 MHz CPU,462 DMIPS/2.14 DMIPS/MHz (Dhrystone 2.1) and DSP instructions, Art Accelerator, L1 cache, SDRAM
   9 * 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
  10 * OSD on board
  11 * The 16M byte SPI flash on board for data logging
  12 * USB VCP and boot select button on board(for DFU)
  13 * Stable voltage regulation,DUAL BEC  5v/2.5A and 10v/2A for VTX/camera etc.And could select 5v/10v with pad
  14 * Serial LED interface(LED_STRIP)
  15 * VBAT/CURR/RSSI sensors input
  16 * Suppose IRC Tramp/smart audio/FPV Camera Control/FPORT/telemetry
  17 * Supports SBus(built-in inverters), Spektrum1024/2048, PPM
  18 * Supports I2C device extend(baro/compass/OLED etc)(socket)
  19 * Supports GPS (socket)
