- 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.
|MCU||216MHz, 32-bit ARM M7 STM32F765II|
|Secure Element||A71CH (I2C4)|
|microSD Card||PX4 Supported SD Cards SDHC version 2 up to 32GB|
|Outputs||6 LEDs (2xRGB)|
|8 PWM Channels|
|Extra Interfaces||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
|PX4 Version||Orientation to Achieve Forward||Branch||Notes|
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
