Amazon Astro Teardown: Part Number Request for BOM Documentation

Hello iFixit team and community,

We are compiling a complete, independent Bill of Materials (BOM) for the Amazon Astro, and your teardown is the only resource that has detailed the hardware. To complete our documentation, we are asking if the teardown team recorded the specific, proprietary part numbers for the following major components:

1. Motors and Actuators:

• Main Drive Motors: The full model number or manufacturer code stamped on the main brushless motors/gearboxes that power the two drive wheels.
• Head/Screen Motors (Pan/Tilt): The model numbers for the smaller motors used to control the screen's horizontal (pan) and vertical (tilt) movement.
• Periscope Mast Motor: The model number for the motor/actuator assembly responsible for extending and retracting the periscope camera mast.

2. Battery System:

• Individual Cells: The exact manufacturer's cell model number (e.g., Samsung, LG, or Sony model) stamped on the individual 18650 cells removed from the main A1440 battery pack.

3. Main PCBs (for unlisted ICs):

• Main Logic Board: Were there any small, unidentified or proprietary Integrated Circuits (ICs) (besides the main Qualcomm processors already listed) whose markings were recorded? Specifically, ICs related to motor control, power management (PMICs), or wireless communication.

4. Proprietary Modules:

• Periscope Camera Module: The part number or manufacturer code on the housing of the custom periscope camera assembly.
• Lidar/Depth Module: Any markings on the Time-of-Flight or Lidar sensor module if it appeared to be a custom part.

Any of these proprietary part numbers would be a massive contribution to fully documenting this complex device. Thank you for your continued work and any information you can share!"
