- Flight Core Functional Description
ModalAI Flight Core is a PX4 flight controller that uses a very similar architecture to FMUv5x. It’s design goal is to be software compatible with the FMUv5x architecture in a smaller Pixracer-style form factor.
|216MHz, 32-bit ARM M7 STM32F765II
|PX4 Supported SD Cards SDHC version 2 up to 32GB
|6 LEDs (2xRGB)
|8 PWM Channels
|3 serial ports
The following is a ‘top down’ view of the Flight Core depicting the orientation. Starting in PX4 v1.11, the orientation is updated to better align with the usage of the VOXL-Flight. The following is a ‘top down’ view of the Flight Core depicting a
|Orientation to Achieve Forward
A 5VDC supply is required to power the Flight Core. The
FC-PM Power Module board is recommended, which provides battery voltage and amperage monitoring through an I2C interface when connected to
J6 using the
Other connectors also allow a 5VDC supply to be connected (see connectors page )
- J6 - recommended, provides I2C interace for monitoring
