  11 ## Hardware Features
  12
  13 * No compromise I/O. Use all the features all the time; e.g. Connect your OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + Sonar + 8 motors - all at the same time!
  14 * On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork. (Acro and Deluxe)
  15 * Next-generation STM32 F3 processor with hardware floating point unit for efficient flight calculations and faster ARM-Cortex M4 core.
  16 * Stackable design - perfect for integrating with OSDs and power distribution boards.
  17 * 16 PWM I/O lines for ESCs, Servos and legacy receivers. 8 available on standard pin headers. 8 via side mounted connectors.
  18 * Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. No external inverters required (built-in).
  19 * Dedicated output for programmable LEDs - great for orientation, racing and night flying.
  20 * Dedicated I2C port for connection of OLED display without needing flight battery.
  21 * Battery monitoring ports for voltage and current.
  22 * Buzzer port for audible warnings and notifications.
  23 * Solder pads in addition to connectors for Sonar, PPM, RSSI, Current, GPIO, LED Strip, 3.3v,
  24 * Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.
  25 * Symmetrical design for a super tidy wiring.
  26 * Wire up using using pin headers, JST-SH sockets or solder pads. Use either right-angled or straight pin-headers.
  27 * Barometer mounted on the bottom of the board for easy wind isolation.
