ModalAI Flight Core is a Pixhawk FMUv5x-derived flight controller. It’s goal is to be software compatible with the FMUv5x architecture in a smaller Pixracer-style form factor.
|MCU||261MHz, 32-bit ARM M7 STM32F765II|
|Secure Element||A71CH (I2C4)|
|microSD Card||Information on supported cards|
|Outputs||6 LEDs (2xRGB)|
|8 PWM Channels|
|Extra Interfaces||3 serial ports|
The following is a ‘top down’ view of the FMU depicting a
A 5VDC supply is required to power the FMU. The
VOXL-PM regulator board is recommended, which also provides battery voltage and amperage monitoring through an I2C interface.
Multiple connectors allow a 5VDC supply to be connected (see connectors page )
- J6 - recommended
NOTE: The following is preliminary data.
