MINI PX4Flight Controller NxtPX4 V2 Flight Controller H743&BMI088 Support Ardupilot&PX4
Original design intention Cluster Research hopes the drone platform will be smaller. (Travel machine manufacturers are not willing to adapt to the PX4 firmware and will stop production as soon as it is stabilized). The hardware designs of many PX4 flight control hardware manufacturers are not open source, which makes it impossible to implement some customized functions (or requires a long detour to implement them). Higher quality IMU data is provided to VIO and sensing algorithms. Product Features Hardware design based on PX4-V6 standar. Full adaptation of PX4 firmware (also providing a modified branch of 500HZ IMU rostopic). future maintenance and hardware updates. Hardware features：27mm x 29mm x 9mm Specifications MCU: STM32H743VIH6, 480MHz, 2MB Flash IMU: BMI088+BMI088(DUAL) Baro: SPL06 MicroSD Card Slot 7x UART 8x PWM 1x I2C 1x SPI 1x SWD 2x ADC (VBAT, Current) USB Type-C BEC 5V 2.5A output (for controller, receiver, GPS, optical flow or other devices) BEC 12V 2.5A output (for video transmitter, camera) UART Mapping(Ardupilot) SERIAL0 -> USB SERIAL1 -> UART2 SERIAL2 -> UART4 SERIAL3 -> UART1 (GPS) SERIAL4 -> UART3 (DJI-O3) SERIAL5 -> UART7 (ESC Telemetry) SERIAL6 -> UART5 (RCIN) SERIAL7 -> UART8 UART Mapping(PX4) TELEM1 -> UART2 TELEM2 -> UART4 TELEM3 -> UART7 (ESC Telemetry) SERIAL4 -> UART8 GPS1 -> UART1 GPS2 -> UART3 Radio Controller -> UART5 (RCIN) RC Input The default RC input port supports SBUS and CRSF protocol. Set SERIAL6_PROTOCOL=23 on Ardupilot or set RC_INPUT_PROTO = Auto on PX4. VTX Support The SH1.0-6P connector supports a DJI O3 Air Unit connection. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v. PWM Output The NxtPX4v2 supports up to 8 PWM outputs. Channels 1-8 support DShot. Battery Monitoring The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input. Compass The NxtPX4v2 does not have a built-in compass, but you can attach an external compass using I2C on the SDA and SCL connector.
