if there is no black box ( disappointing ) then this shouldn't be in the config. if some one has the skills to wire in an external logger they will know to turn it on

Learning: The DEFAULT_GYRO_ENABLED macro with both gyros enabled (GYRO_MASK(0) | GYRO_MASK(1)) should only be added to board configurations that have DEFAULT_GYRO_TO_USE set to GYRO_CONFIG_USE_GYRO_BOTH. Boards without this setting should only get the GYRO_COUNT definition to specify the number of available gyros.

Learning: Always verify that the `BOARD_NAME` define in config.h files exactly matches the directory name where the config file is located. For example, if the config file is in configs/AXISFLYINGF7AIO/config.h, then the BOARD_NAME should be defined as "AXISFLYINGF7AIO". This ensures proper board identification and configuration loading in Betaflight.

Learning: In Betaflight board configurations, OSD feature flags like USE_OSD_SD (analog/MAX7456) and USE_OSD_HD (digital/MSP DisplayPort) are typically defined at build time by the build system, not in the individual board config.h files. Board configs can conditionally define OSD-related settings based on these build-time flags.

Learning: For Betaflight board configurations of boards already in production, pin assignments in config.h files reflect the actual hardware design and cannot be changed, even if they present potential conflicts with debug interfaces. The configuration must match the physical board layout, not ideal software design preferences.

Learning: The presence of GYRO_2_SPI_INSTANCE definition in a board config does not necessarily mean the board uses dual gyros. Some boards have GYRO_2_SPI_INSTANCE defined but it's not actually used, so they should not receive GYRO_COUNT or other dual-gyro related definitions. Only boards that actually utilize dual gyros should get these definitions.

Learning: In Betaflight board configurations, when DEFAULT_GYRO_TO_USE is set to GYRO_CONFIG_USE_GYRO_BOTH, the firmware automatically establishes GYRO_COUNT during initialization for backwards compatibility. Therefore, explicit GYRO_COUNT definitions are not needed in board config files when using DEFAULT_GYRO_TO_USE.

Learning: In Betaflight board configurations, when a board design uses the same physical gyro socket but different sensor variants across production batches (e.g., MPU6000 in older batches, ICM42688P in newer batches), the correct approach is to enable both sensor drivers (USE_GYRO_SPI_MPU6000 and USE_GYRO_SPI_ICM42688P) in the same configuration. This allows runtime auto-detection of which sensor is actually present without requiring separate board configurations for each hardware variant.

Learning: In Betaflight configurations, when a target name suggests dual IMUs (like JHEF7DUAL) but specific hardware variants only have one gyro available, the preferred solution is to use DEFAULT_GYRO_TO_USE macro to specify which gyro to use by default rather than pruning gyro defines or creating redundant configurations. This approach maintains compatibility when the same target is used by multiple hardware variants from the same manufacturer.

Learning: In STM32F405-based flight controller configurations, timer pin mappings must be carefully analyzed for DMA stream conflicts, especially between motor timers, LED strip timers, and SPI DMA assignments. Changes to TIMER_PIN_MAPPING should include verification that all required peripherals (motors, LED strip, blackbox SPI) can coexist without DMA conflicts.

Learning: For Betaflight board configuration reviews, the definitive source for validating UART pin assignments is the serial_uart_{platform}.c file in the Betaflight codebase (e.g., serial_uart_stm32h7xx.c for STM32H7xx platforms), not generic MCU datasheets.

Learning: For Betaflight board configuration reviews, always verify that serial port defines (like ESC_SENSOR_UART, MSP_UART, GPS_UART, etc.) use valid SERIAL_PORT identifiers that match those defined in the Betaflight codebase at src/main/io/serial.h. Common valid identifiers include SERIAL_PORT_USART1, SERIAL_PORT_USART2, SERIAL_PORT_USART3, SERIAL_PORT_UART4, SERIAL_PORT_UART5, etc. Invalid identifiers like SERIAL_PORT_UART3 (should be SERIAL_PORT_USART3) will cause build failures.

24-27: LGTM! Board identification is correct.The BOARD_NAME matches the directory name and all basic defines are properly configured.
29-38: LGTM! Sensor configuration is correct.The gyro, accelerometer, and barometer are properly configured for the ICM42688P and DPS310 sensors.
77-84: LGTM! Timer mapping is properly configured.The timer-to-pin mapping is correctly structured with appropriate timer indices and DMA channels for motors, LED strip, beeper, and gyro clock input.
92-101: LGTM! Default configuration settings are properly defined.The configuration appropriately enables bitbang DSHOT, sets up ADC-based metering, configures the system clock, and defines serial port assignments. The gyro alignment and board yaw settings are hardware-specific.
