Mapping schematics to the device tree's source

Because the BeagleBone Black's Bill Of Materials (BOM), PCB design files, and schematics are all open source, anyone can manufacture a BeagleBone Black as part of their consumer product. Since the BeagleBone Black is intended for development, it contains several components that may not be needed for production, such as an Ethernet cable, a USB port, and a microSD slot. As a dev board, the BeagleBone Black may also be missing one or more peripherals needed for your application such as sensors, an LTE modem, or an OLED display.

The BeagleBone Black is built around Texas Instruments' AM335x, a single core 32-bit ARM Cortex-A8 SoC with dual Programmable Real-Time Units (PRU). There is a more expensive Wireless variant of the BeagleBone Black made by Octavo Systems that swaps out Ethernet with a Wi-Fi and Bluetooth module. The BeagleBone Black Wireless is also open source hardware, but at some point, you may want to design...
