Alta X Brain Bay
Located in Alta X Bay 2
The Brain Bay is the nerve centre between the Alta X Flight Controller, the HD FPV Camera Bay and the additional PWM Outputs.
The three user-configurable PWM outputs are accessible via the PWM/SBUS Breakout Wire Harness, which connects to the rear of the Brain Bay Circuit Board. These outputs provide flexible control options, enhancing the system's versatility and functionality.
Included in the Brain Bay Kit
1x Brain Bay Housing and PCB

How to Power the Brain Bay
Power Input Connection
Power Input Cables:
Use either the supplied XT60 or XT30 cable.
Recommended: Use the Freefly Systems 12V DC to DC Regulator for Alta X (tested and recommended)
Alternatively, connect the Brain Bay Power Input Cable (XT60 or XT30) to a 7.4V - 25.2V power source. Plug the JST-PH 2-pin connector into the Brain Bay power input.
Brain Bay Power Input:
Plug the JST-PH 2-pin connector into the brain bay power input within the Alta X.
Warning: The Brain Bay must be powered by a 2S-6S power source (7.4V - 25.2V). Connecting the Brain Bay to ALTA X flight packs will cause permanent damage to both the Brain Bay and HD VTX.

Brain Bay PWM Outputs
MAVTx and the Alta X Brain Bay allow the user to access and adjust the settings for three generic PWM outputs on the back of the Brain Bay. The PWM outputs are controlled via radio channels on the users control radio. This includes seamless integration with the XM2 Retractable Landing Gear (PWM1), enhancing safety features such as preventing retraction when the drone is not airborne and automatically lowering the legs during auto-landings (when activated).
Once a radio channel has been assigned to a PWM channel, the raw radio PWM value will be output on the corresponding PWM channel as a standard 50 Hz PWM signal. The current output value of each channel is available to be displayed in the OSD as well through the PWM1, PWM2, and PWM3 OSD elements. If the PWM channel is set to disabled, then that channel will not output a pulse. If the Alta X experiences a radio failsafe, all PWM channels will cease to output a pulse. Once the settings have been adjusted, navigate to the “EXIT TO MENU >” line and press right on the Brain Bay Joystick to be returned to the main OSD menu.
