+# SpeedyBee F405 v3 Flight Controller
+
+The SpeedyBee F405 v3 is a flight controller produced by [SpeedyBee](http://www.speedybee.com/).
+
+## Features
+
+ - STM32F405 microcontroller
+ - BMI270 IMU
+ - DPS280 barometer
+ - SDCard
+ - AT7456E OSD
+ - 6 UARTs
+ - 9 PWM outputs
+
+## Pinout

+
+## UART Mapping
+
+The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the
+receive pin for UARTn. The Tn pin is the transmit pin for UARTn.
+
+ - SERIAL0 -> USB
+ - SERIAL1 -> UART1 (DJI-VTX, DMA-enabled)
+ - SERIAL2 -> UART2 (RCIN, DMA-enabled) 
+ - SERIAL3 -> UART3 (CAM)
+ - SERIAL4 -> UART4 (connected to internal BT module, not currently usable by ArduPilot)
+ - SERIAL5 -> UART5 (ESC Telemetry)
+ - SERIAL6 -> UART6 (GPS, DMA-enabled)
+
+## RC Input
+
+RC input is configured on the R2 (UART2_RX) pin for most RC unidirectional protocols except SBUS which should be applied at the SBUS pin. PPM is not supported.
+For Fport, a bi-directional inverter will be required. See https://ardupilot.org/plane/docs/common-connecting-sport-fport.html
+For CRSF/ELRS/SRXL2 connection of the receiver to T2 will also be required.
+ 
+## FrSky Telemetry
+ 
+FrSky Telemetry is supported using the Tx pin of any UART including SERIAL2/UART2. You need to set the following parameters to enable support for FrSky S.PORT (example shows SERIAL3).
+ 
+  - SERIAL3_PROTOCOL 10
+  - SERIAL3_OPTIONS 7
+  
+## OSD Support
+
+The SpeedyBee F405 v3 supports OSD using OSD_TYPE 1 (MAX7456 driver).
+
+## VTX Support
+
+The JST-GH-6P connector supports a standard DJI HD VTX connection. Pin 1 of the connector is 9v so be careful not to connect
+this to a peripheral requiring 5v.
+
+## PWM Output
+
+The SpeedyBee F405 v3 supports up to 9 PWM outputs. The pads for motor output
+M1 to M4 on the motor connector, plus M9 for LED strip or another
+PWM output.
+
+The PWM is in 3 groups:
+
+ - PWM 1-4 in group1
+ - PWM 5-8 in group2
+ - PWM 9 in group3
+
+Channels within the same group need to use the same output rate. If
+any channel in a group uses DShot then all channels in the group need
+to use DShot. Channels 1-4 support bi-directional DShot.
+
+## Battery Monitoring
+
+The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input.
+The voltage sensor can handle up to 6S.
+LiPo batteries.
+
+The default battery parameters are:
+
+ - BATT_MONITOR 4
+ - BATT_VOLT_PIN 10
+ - BATT_CURR_PIN 11
+ - BATT_VOLT_MULT 11.2
+ - BATT_AMP_PERVLT 52.7 (will need to be adjusted for whichever current sensor is attached)
+
+## Compass
+
+The SpeedyBee F405 v3 does not have a builtin compass, but you can attach an external compass using I2C on the SDA and SCL pads.
+
+## Loading Firmware
+
+Initial firmware load can be done with DFU by plugging in USB with the
+bootloader button pressed. Then you should load the "with_bl.hex"
+firmware, using your favourite DFU loading tool.
+
+Once the initial firmware is loaded you can update the firmware using
+any ArduPilot ground station software. Updates should be done with the
+*.apj firmware files.
