|These are GPIO pins directly connected to the Core Avionics. These can be used to transfer a digital signal to the avionics, have the avionics sample an analog signal, or have the avionics PWM a signal, depending on the specific GPIO pin used. If this functionality is desired, one should reference the Core Avionics schematic to determine the pin capabilities of each of the GPIO's. These can be used both as inputs (to the Core Avionics) or outputs (from the Core Avionics). On the schematic symbol for the HABEES stackup, these are referred to as "AV____" where ____ is the corresponding pin on the Main Avionics MCU (a teensy 3.6). Reference the ____ pin on the 3.6 schematic to determine its functionality.

|This pin is pulled high by the BlueJay RockBlock breakout board -- to signal to the main avionics that it is in use, as opposed to the on-board 9603 modem.
