Mobile Audio Module board

Mobile audio module (MAM)

pcb

This project includes board scheme and manufacturing details. Current revision is 1.1. Board main features:

• Input power range 14V..28V
• Reserve 4.2V Accumulator power source for MPU
• Internet connection using onbard 4G LTE (SIM card needed)
• GPS connection (3V external antenna needed)
• AUDIO In (microphone input can be routed to amplified audio out)
• AUDIO Out Amplified (ready for external speaker use)
• External Memory storage (uSD card)
• ADB console (microUSB)
• Open-Linux programmable board

Dependencies

PCB development is performed using Altium Designer 19 or versions higher. Components library is linked as separate submodule:

git submodule init
git submodule update
cd pcb/libs
git checkout master

Manufacturing and assembly

Current project provides all necessary files for pcb order:

• Bill of materials (BOM)
• Gerber files
• Assembly drawings

Files mentioned above are located in: ./pcb/vX.X/Project Outputs for Autoinformer_vX.X/

where X.X is version of the board. The lastest version for now is 1.1.
