Features: JTAG/SWD isolator is a tool used to protect the debugger and computer. When debugging or burning the single chip computer on the circuit board with high voltages, carelessness will leads to high voltages backflow to the computer, and even the data of the hard disk will be lost. This isolator can completely isolate the debugger and the targets board electrically, providing ensures for debugging the high-voltages board. Essential for embedde systems engineers, hardware developers, and industrial automation technicians working with power electronic or motor control systems requiring safe voltages separation. Safely debugs 220V+ industrial control boards, automotive, and renewable energy inverters without risking damage to sensitive USB debuggers or workstations components.
