J-Trace Isolator

The J-Trace Isolator can be connected between a J-Trace and any Arm board that uses the standard 19-pin Cortex-M connector. It provides electrical isolation while keeping high speed trace capabilities. This is essential when the development tools are not connected to the same ground as the application. It also protects the development tools from electrical spikes that often occur in some applications, such as motor control. Another typical field of application is the development of products with sensors or other analog circuitry. In this case, the J-Trace Isolator protects target hardware from electrical noise originating from the development PC.
