SEQURE H743 V2 & E130/E160 G2 4-12S FPV Stack

Because burning out your standard 6S flight stack on a heavy-lift rig wasn't expensive enough, SEQURE dropped this absurdly over-engineered solution. Packed with an STM32H743 processor running at a blistering 480MHz and paired with a monster 4-12S ESC, the SEQURE H743 V2 stack gives your cinematic quad or X8 octocopter the processing grunt and thermal headroom it actually needs. Featuring a low-noise ICM42688P gyro, 16MB blackbox logging, and a dedicated 10V BEC for your DJI O3/O4 HD VTX, this stack stops you from turning expensive gear into magic smoke. We've spent a decade bench-testing FPV gear in the UK, and this is proper industrial-grade overkill for pilot specs that demand zero compromises.

Highlights

• STM32H743 Processing Power: 480MHz clock speed to handle complex filtering algorithms and high looptimes without sweating.
• 12S High Voltage Handling: Up to 53V input on the E130/E160 G2 ESC. For 9–12S builds, bridge the ESC’s V pad to V+ to feed the H743 V2 from the regulated 16V BEC, not raw battery voltage. The FC itself is rated for 4–8S.
• DJI O3/O4 Plug-and-Play: Dedicated SH1.0 port delivering filtered 10V/2A power directly to HD digital video transmitters.
• Precise ICM42688P Gyroscope: Ultra-clean IMU sensing for rock-solid flight stability and razor-sharp sticks feel.
• 8 Motor Outputs: The FC has eight motor signal outputs for X8 builds. The included 4-in-1 ESC drives four motors; an X8 needs four additional ESC channels.

Why You Want It

If you're tired of ESCs whimpering the moment you push past 6S voltage or load up Betaflight with aggressive RPM filtering and INAV/ArduPilot telemetry, this stack is your cure. It delivers absurd continuous current handling (up to 160A) and enough UARTs to wire up every peripheral you own without needing a master's degree in compromise.

FAQ

Can I run ArduPilot or INAV on this flight controller?

Yes, the SEQURE H743 V2 natively supports Betaflight (default), INAV, and ArduPilot under the SEQUREH7V2 target.

Is this stack compatible with DJI O3 and O4 Air Units?

Yes, it features a plug-and-play connector wired directly to an onboard filtered 10V/2A BEC designed for HD digital VTXs.
