FLYWOOF7DUAL
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 ICM20689,could choose mpu6000,more stable and smooth.Or choose ICM20689,higher rate(32K/32K).Choose on CLI mode,experience different feature gyro on same board
- 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/SmartAudio/FPV Camera Control/FPORT/telemetry
- Supports SBus, Spektrum1024/2048, PPM. No external inverters required (built-in).
- Supports I2C device extend(baro/compass/OLED etc)(socket)
- Supports GPS (socket)
All uarts have pad on board
