NOTE!!! The firmware for MSP430-JTAG is not maintained anymore due to hardware restraints. Version is the last version of the drivers. The product is not recommended for new designs! Please consider MSP430-JTAG-TINY-V2 or MSP430-JTAG-ISO-MK2.


  • Programs all MSP430Fxxx flash microcontrollers (note: parallel port JTAG doesn't support Spy-Bi-Wire devices because timing from the parallel port can't meet programming specs)
  • Uses TI standard 2x7 pin JTAG connector
  • No need for external power supply, all power is taken from the LPT port
  • Compatible with software tools that have support for MSP430 Debug Stack version 2 (MSP430.dll v2).
  • Not compatible with newest versions of Code Composer Studio (6.1.3 and after)
  • Limited compatibility with IAR Embedded Workbench for MSP430, but not compatible with latest versions of IAR EW for MSP430 (6.x.x and after). IAR EW for MSP430 is a commercial software for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump etc everything all high priced emulators do. With IAR Kickstart you can write in assembler unlimited code size and to write in C with 2K limit for all MSP430 microcontrollers
  • Works with free GCC C compiler and Insight MSP430 toolchain and debugger
  • Dimensions 50x40 mm (2x1.6") + 20 cm (8") cable



  • Can I use MSP430-JTAG with Windows Vista, Windows 7 and/or Windows 8?
  • There isn't such support. Generally, Olimex LPT products can be used up to Windows XP. Any newer Windows would require a virtual machine running XP.
  • Can I use MSP430-JTAG with XYZ development IDE/tools?
  • Compatible with software tools that have support for MSP430 Debug Stack version 2 (MSP430.dll v2). Most tools nowadays have switched to MSP430 Debug Stack version 3 so this product would not be supported.
  • What amount of current MSP430-JTAG can source to the target circuit?
  • No more than 2-3 mA. It takes power from the parallel port, so it's quite limited, of course this is still good to run some small MSP430 targets circuits.
  • Why is the ribbon cable so small? My computer is 1 meter away from my target circuit?
  • The ribbon cable should be short. Please use DB25 parallel port extension cables male-female to connect MSP430-JTAG to your printer port.
  • Other companies charge money for MSP430 programming software, why is yours free?
  • To write MSP430 programming software using the TI MSP430.dll is a very easy job, there would probably be tons of such programmers available if TI was not keeping the DLL content secret. The programmer software we offer is a beta testing software so it may have some bugs although we've been using it for years at home. Now we've decided to release it for the public as we got a number of questions about whether we know of any such software :). As we are a more hardware-oriented company rather than software-oriented and we've never gotten involved in sales of software, we decided to just release it as a freeware and not to hassle with software copy protections and such.Note that it's not open source but a copyrighted software, although it costs you nothing to obtain or distribute it. We are going to fix all reported bugs in a timely manner but keep in mind that it's not a commercial project and our people have a lot of other stuff to do.
