Add configuration file for NYX743V1 board

[Nyxtronics]

Pull-Request requirements

Mandatory Review for All New Flight Controllers

• All new flight controllers must undergo the Betaflight review process, regardless of whether they use an existing target.
• Manufacturers may reuse the same target for multiple designs, but each new hardware release must be reviewed before approval.

Hardware Compliance Requirements

• All hardware must adhere to the Manufacturer Design Guidelines.
• Poor hardware designs will not be accepted, as outlined in the Requirements for the Submission of New and Updated Targets.
• Adhere to the [Config Target Guidance] https://betaflight.com/docs/development/manufacturer/config-target-guidance
• To avoid costly issues and delays, we strongly encourage consulting with Betaflight developers early in your design process and providing schematics for review before producing hardware.

These measures help maintain high standards and ensure compatibility within the Betaflight ecosystem.

If you have any questions or need guidance, feel free to reach out to the Betaflight development team.

Checklist (✓/✕, or y/n)

• passed Betaflight team's schematics review
• passed hardware samples testing
• follows guidelines
• follows connector standards
• flight tested
• comments/issues resolved

Walkthrough

The pull request adds a configuration for the NYXT NYX743V1 STM32H743 flight controller. It specifies supported sensors and peripherals, board pin and timer mappings, ADC DMA options, and default settings.

Changes

NYX743V1 board configuration

Layer / File(s)	Summary
Board features and hardware mapping configs/NYXT/NYX743V1/config.h	Enables sensor and peripheral support, assigns board pins, and defines timer mappings and ADC DMA options.
Peripheral and default settings configs/NYXT/NYX743V1/config.h	Sets I2C instances, blackbox and ADC meter defaults, gyro and display SPI settings, PINIO box assignments, and UART5 ESC sensor data.

Merge Risk | ⚪ Minimal · up to 75b3c

Merge Risk: ⚪ Minimal · up to 75b3c

No established issue currently blocks merging this target configuration.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 75b3c

The change is confined to one board configuration, with no demonstrated expansion of privileges or confirmed security weakness. Startup behavior and restoration of stored settings for the power-control output remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The directly evidenced control scope is hardware running the selected NYX743V1 firmware and its connected outputs, including the 12V BEC. Downstream consequences depend on attached equipment and runtime behavior not established by this header.

Trust Boundaries and Controls

• observed — The configuration declares physical UART, sensor-bus, and CAN pin bindings. These declarations do not establish input authentication, parser behavior, or effective CAN enablement; the relevant controls reside in firmware consumers not inspected for this pass.

Inline comments:
Review comments at @configs/NYXT/NYX743V1/config.h:
- Line 100: Set PINIO_COUNT to 8 in this configuration alongside PINIO5_PIN so
Betaflight registers the fifth PINIO pad.
- Line 111: Rename the CAN1 transmit-pin macro in the target configuration from
CAN1_TX_PIX to CAN1_TX_PIN, keeping its PB9 value so CAN1 recognizes the
configured TX pin.
