        Reverse Engineering Tesla Hardware
        Overview of the Tesla Hardware
        Let’s take a look at the individual components
        CID Hardware Architecture
        Visual Compute Module
        Ethernet Switch
        Gateway
        Cellular Modem
        Wi-Fi Module

        Wi-Fi and Bluetooth Gateway interface between VCM and the various CAN buses Full-sized 4GByte SD card connected to firmware gateway Nvidia VCM (Visual Computer Module); ARM-based single board computer, with integrated 2 GB RAM, 8 GB NAND flash, 64MB NOR flash, and various peripherals Ethernet switch 16GByte microSD connected to VCM for mapping data 3G modem for cellular connectivity Assorted other modules including FPGA for display glue logic
        The CID and IC are connected by both Ethernet and CAN bus.
        An NVidia VCM (Visual Compute Module) sits at the core of the CID.
        Nvidia VCM modules are used in both the CID and IC.
        Even without direct manuals for the VCM or Tegra SoC, development boards often contain schematics and pin-outs for supplied modules, and spares for destructive tests.
        SMSC USB to Ethernet controller LAN89530AM – for the Ethernet connection out to the switch SMSC Automotive USB transceiver USB83340 – for USB connections out to the rest of the CID Spansion 64Mibyte NOR Flash GL512S11DHA02 –storage for the kernel and bootloaders
        An unpopulated 8-way header, J1 An unpopulated footprint for LQFP100 package An unpopulated footprint for TSOP48 package (most likely parallel NAND flash as an alternative to eMMC) TI power management unit TPS65829I Nvidia Tegra SoC T20AGS-SH-A4 – a Tegra 2 not a Tegra 3 in the CID; this is probably because the screen is smaller and requires less power.
        SK Hynix 4GiByte eMMC NAND Flash H26M31001FRP1 – 50% less than the CID SK Hynix 1GiBit H5PS1G83KFR – there are eight, giving 1GiByte of RAM, 50% less than the CID SMSC USB to Ethernet controller LAN89350AM SMSC Automotive USB transceiver USB83340 Spansion 64MiByte NOR Flash GL512S11DHA02
        Despite further examination of the Tesla, we did not uncover any functionality for tracking or eCall running on the CID’s VCM
