Designed by Grand Idea Studio, JTAGulator is an open source hardware tool that assists in identifying OCD connections from test points, vias, or component pads on a target device. On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available OCD connections can be a difficult and time consuming task, sometimes requiring physical destruction or modification of the device. Key Features: 24 I/O channels with input protection circuitry Adjustable target voltage: 1.2 V to 3.3 V Supported target interfaces (as of firmware v1.1): JTAG/IEEE 1149.1, UART/asynchronous serial USB interface for direct connection to host computer (PC, Macintosh, or *nix) The JTAGulator is powered from the host computer’s USB port and uses an industry-standard FTDI FT232RL device to provide the USB connectivity.
