Why NxtPX4

A smaller flight controller for compact research and swarm airframes, without giving up an H7 processor and dual IMUs.
Open hardware design — the schematics are public, so custom functions can be added without reverse-engineering the board.
Higher-quality IMU data for VIO and perception algorithms.

Product Features

Hardware design based on the Pixhawk FMU-V6 standard.
Full PX4 support (a modified branch with a 500 Hz IMU ROS topic is also available).
Ongoing firmware maintenance and hardware updates.
Size: 27 × 32 × 8 mm on a 20 × 20 mm mount.

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.

Note: the peripheral power outputs stay off when the board is powered from USB alone. If the ground station connects but cannot see an external compass or other peripheral, plug in the main battery first and check again.
