FlySpark F4 V1 Flight Controller

A: The FlySpark F4 V1 is an FPV drone flight controller built around the STM32F405 processor and ICM-42688-P gyro. It is designed for racing drones, freestyle quadcopters, drone-show builds, professional multirotors and custom UAV platforms.

A: The listed import price is 7,500 ₹ for the FlySpark F4 V1 Flight Controller Standard Unit. Final pricing may vary if setup support, ESC pairing, wiring assistance or digital FPV integration is added.

A: It uses an STM32F405 MCU, a widely used F4-class processor for FPV flight controllers and multirotor control systems.

A: The FlySpark F4 V1 uses the ICM-42688-P IMU / gyro for flight stabilization and motion sensing.

A: Yes, the board includes a built-in DPS310XTSA1 barometer, supporting altitude-related flight functions depending on firmware and configuration.

A: Yes, it includes the MAX7456EUI+ OSD chip for analog FPV on-screen display support.

A: Yes, Bluetooth is supported for configuration. The FlySpark specification notes MSP enabled at 115200 baud on UART4.

A: No, Wi-Fi is not supported. Bluetooth is available for supported configuration workflows.

A: The board supports Betaflight by default and is also compatible with INAV, EMU-Flight, ArduPilot and SkyBrush depending on setup and target configuration.

A: Yes, the board supports DJI Air Unit connection through a 6-pin connector or direct soldering. It is compatible with DJI O3, RunCam Link and Caddx Vista style digital FPV systems.

A: Yes, the board has a MicroSD card slot for blackbox logging. It supports SDSC and SDHC cards up to 32GB, while Betaflight may recognize a maximum of 4GB.

A: The FlySpark F4 V1 supports 3S–6S LiPo power input.

A: The board provides 5V outputs, 9V outputs, 3.3V output and 4.5V output for peripherals. Current limits should be followed carefully during wiring.

A: The board has 6 UART sets: UART1, UART2, UART3, UART4, UART5 and UART6. UART4 is used for Bluetooth and UART5 can support ESC telemetry.

A: Yes, I2C is supported through SDA and SCL pads on the front side. It can be used for compatible magnetometer or sonar peripherals.

A: Yes, BZ+ and BZ- pads are available and support 5V buzzers.

A: Yes, RSSI input is supported through the RS pad on the front side.

A: ESC signal outputs M1–M4 are on the bottom side, while M5–M8 are on the front side. This allows flexible wiring for different multirotor layouts.

A: The board uses a 30.5 × 30.5 mm mounting pattern with 4 mm mounting holes, making it compatible with many FPV frames and stacks.

A: The board dimensions are 41.6 mm length × 39.4 mm width × 7.8 mm height.

A: The listed weight is 10.5 g, making it suitable for lightweight FPV and professional multirotor builds.

A: Yes, it is designed to work well with the FlySpark BLS 60A 4-in-1 ESC. For current sensor input with that ESC, the specification recommends scale 400 and offset 0.

A: The board can be used by beginners with proper guidance, but FPV flight-controller wiring, firmware setup, receiver configuration, motor mapping and power checks require care. Professional installation is recommended for mission-critical builds.

A: The standard package includes the FlySpark F4 V1 Flight Controller. Accessories, cables, ESC, receiver, GPS, DJI O3 Air Unit, camera, VTX and other build parts should be confirmed separately.

A: Warranty support generally covers manufacturing defects under approved use and normal conditions. Damage from incorrect wiring, reverse polarity, soldering mistakes, crash impact, water exposure, overvoltage or unauthorized modification may not be covered.
