iFlight Borg H7 4–12S FPV Flight Controller

The iFlight Borg H7 is an STM32H743-based flight controller intended for 5–10-inch FPV drone builds. Its listed 4–12S input range, dual ICM42688 gyros, and dual camera inputs provide several options for planning your electronics and FPV setup.

Match the mounting pattern, power requirements, ESC connection, and firmware to your build before installation. Drone size alone does not establish compatibility.

Key Features

• ✅ 4–12S Input — The listed input range includes LiHV support; confirm every connected component's voltage requirements separately.
• ✅ H7 Processing and Dual Gyros — STM32H743VIH6 MCU with two ICM42688 gyros and 32MB Blackbox flash.
• ✅ Dual Camera Inputs — Supports camera switching through transmitter configuration, subject to correct wiring and firmware setup.
• ✅ Switchable VTX Supply — Listed 12V 2A BEC with VTX switching, alongside a 5V 2.5A BEC.
• ✅ Connection Options — FPC connection for the ESC and SH1.0 locking connections for other interfaces; verify pinouts before connecting.
• ✅ Peripheral Expansion — Seven UARTs, eight motor outputs, two I2C interfaces, LED control, and a beeper pad.

Wiring and Installation

The original listing suggests the following port assignments. These are planning references, not mandatory assignments for every build.

• UART 1: HD / analog VTX
• UART 2: receiver
• UART 3: GPS or other serial sensors
• UART 4: GPS
• UART 6: ESC telemetry
• UART 7: GPS or other serial sensors
• UART 8: GPS or other serial sensors

Seven available UARTs are listed as UART 1, 2, 3, 4, 6, 7, and 8. Choose assignments for your actual peripherals rather than treating all suggested GPS connections as required.

⚠️ Remove propellers before bench configuration. Disconnect power before wiring, check polarity and connector pinouts, and match the ESC's FPC connection to this board. Connector shape alone does not establish electrical compatibility. Verify the board revision and firmware target before flashing.

Labeled board-pad reference; verify the pinout for your board revision before wiring.

Configuration Reference

These command blocks are retained from the supplied product listing for reference. Their pin assignments, mode identifiers, and AUX ranges have not been independently validated for every firmware version. Back up your configuration and check the current board-specific instructions before applying them. Configure transmitter channel assignments for your own setup rather than pasting these examples unchanged.
