For higher speeds consider the J-LinkPlus Ultra.. - 1568512: Does it support my IDE?***SIMP***J-Link works with major IDEs (GDB-based and vendor IDEs). If you require Ethernet for remote farms, consider the J-Link Pro.. - 1568513: What target connector does it use?***SIMP***Standard 20-pin 0.1″. For compact headers use adapters such as the 9-pin Cortex-M. - 1568514: How fast is the interface clock?***SIMP***Up to 15 MHz JTAG/SWD; SWO sampling up to 30 MHz for trace/printf-style logging. - 1568516: Can I use it for production flashing?***SIMP***Yes - J-Flash (included) supports production-grade programming. For high-volume, SEGGER Flasher units may be preferable; ask Debug Store for guidance. - 1568517: What CPUs are supported?***SIMP***ARM Cortex-M/R/A and many legacy ARM cores; also Renesas RX and Microchip PIC32 families via J-Link device support. - 1568518: Is there galvanic isolation?***SIMP***Not in PLUS Compact by default. You can add an isolator accessory if required (see Debugger Accessories).
