I got the "Get Started guide/image" here : chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/ https://software.intel.com/sites/default/files/managed/25/d5/Intel-Aero-Compute-Board-Getting-Starte...
And noticed about it addressed there's a 80 pin flexible I/O expansion cable which could supports 3rd party flight controller and accessories (I2C, SPI, USB, UART, GPIOs), however when I checked the expansion cable ports, I only found GPS, compass, telemetry, radio control, and power board ports; so I'm wondering where's the I2C, SPI, USB, UART, and GPIOs that we needed to connect with our owned flight controller(which should be a high speed UART) as well as other accessories(I2C, SPI, USB, UART, GPIOs) ?
If the expansion cable did provided those I/O(I2C, SPI, USB, UART, GPIOs), would you please provide us those pin definition on the expansion cable in each ports ?
We are currently working on documentation, the documentation on the 80-Pin connector should be available soon.
We apologize for any inconvenience this might cause.
