  11 ## Hardware Features
  12
  13 * Next-generation STM32 F3 processor with hardware floating point unit for efficient flight calculations and faster ARM-Cortex M4 core.
  14 * MicroSD-Card socket for black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.
  15 * Race transponder built in - just turn up at a race and have your lap times recorded.
  16 * Features the latest Accelerometer, Gyro and Mag/Compass and Baro/Altitude sensor technology.
  17 * Wire up using using pin headers for all major connections for excellent crash-durability.  Use either right-angled or straight pin-headers.
  18 * No compromise I/O. Use all the features all the time; e.g. Connect your USB + OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + 8 motors - all at the same time!
  19 * 8 PWM output lines for ESCs and Servos. Arranged for easy wiring on standard pin headers.
  20 * Supports direct connection of SBus, SumH, SumD, Spektrum1024/2048, XBus receivers. No external inverters required (built-in).
  21 * Supports direct connection of 3.3v Spektrum Satellite receivers via 3 pin through-hole JST-ZH connector.
  22 * Dedicated PPM receiver input.

  24 * Telemetry port
  25 * Micro USB socket.
  26 * Dedicated output for programmable LEDs - great for orientation, racing and night flying. (Currently mutually exclusive with the Transponder).
  27 * Dedicated I2C port for connection of OLED display without needing flight battery.
  28 * Battery monitoring for voltage and current.
  29 * RSSI monitoring (analogue or PWM).
  30 * Buzzer port for audible warnings and notifications.
  31 * Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.
  32 * Symmetrical design for a super tidy wiring.
  33 * JST-SH sockets only for I2C, UART2 and SWD.  UART2 also on through-hole pins.
  34 * Flashing via USB or serial port.
  35 * Stackable design - perfect for integrating with OSDs and power distribution boards.
  36 * Standard mounting - 36x36mm with standard 30.5mm mounting holes.
  37 * LEDs for 3v, 5v and Status for easy diagnostics.

  45 | 2     | USART2       | PA15         | PA14 / SWCLK | YES         | JST socket and PPM header. Use to connect to RX. |
  46 | 3     | USART3       | PB11 / AF7   | PB10 / AF7   | NO          | Available on 4 through-hole pins. 3.3V signals only ! Use for GPS, Spektrum Satellite RX, SmartPort Telemetry, HoTT telemetry, etc. |
  47
  48 * You cannot use SWD and USART2 at the same time.
  49 * When using a Serial RX receiver the TXD (T2) pin cannot be used for telemetry. Use UART3 TXD instead.
  50 * Two SoftSerial is supported. Enabling SoftSerial disables Servo output 3,4,5,6
  51 * Windows DFU Flashing requires Zadig (see configurator)
