SP Racing F3 FC Board(Deluxe) internal OSD

Specification:

Interface definition

IO_1 connector - PWM RX / PPM RX / GPIO / LED Strip

When using a PWM receiver connect CH1/2/5/6 to PWM RX.

LED Strip data signal can be used to change individual colors of each LEDs on a strip of

WS2812 RGB leds - Perfect for battery warning lights, orientation lights, indicators, failsafe,

display flight modes, etc.

CH1/2/5/6 can be used as a general purpose IOs when not used for PPM/PWM RX.

A 3.3v output is also available.

IO_2 connector - Serial RX / PWM RX / GPIO / UART3

When using a PWM receiver connect CH3/4/7/8 to PWM RX.

When using a 3.3v Serial RX receiver (S.Bus, SUMD/H, etc.) use GND/VCC/CH3 (UART3

RX).

CH3/4/7/8 can be used as general purpose IO when not used for Serial/PWM RX. CH7/8 can be used for a 3.3v Sonar sensor when not used for PWM RX. ADC_1/2 can be used to connect Battery Current Monitoring and RSSI signals. (3.3v MAX). OUTPUT headers - Connect up to 8 motors and/or servos Currently supports PWM ESCs (400hz default), Oneshot 125 ESCs and PWM servos (50hz default). WARNING: Configure outputs before connecting power to servos and ESCs.

F3 SETUP connector – Used for Flashing firmware and configuring the Flight controller by computer with connected to the USB-TTL Serial Converter OSD SETUP connector – Used for Flashing OSD firmware and configuring the OSD SWD/DEBUG connector - Used for software development or flashing via SWD Cannot be used when UART2 is enabled. Use an ST-Link debugger with OpenOCD or a J-Link debugger.

How to install MW OSD firmware to your OSD hardware Preparation •Download the MW OSD software pack of your choice. •Download the Arduino flavor that matches your system. Testing Firmware communication flashing •Connect the OSD to the FTDI adapter, and that to the PC. •Start Arduino IDE. •Choose the appropriate board. For most MinimOSDs etc go to menu Tools > Board > Arduino Pro or Pro Mini 5V, 16MHz, w/ ATmega328. •Select the proper serial port in menu Tools > Serial Port.
