J-Link EDU Base Programmer

The J-Link line of JTAG programmers from Segger is well known for their top of the line debuggers. A low-cost J-Link for educational purposes, the J-Link EDU is identical to J-Link BASE and offers the same functionality. It has been designed to allow students and educational facilities as well as hobbyists access to top of the line debug probe technology. The J-Link EDU is a great option for those getting started with JTAG/SWD programming and debugging, but want a bit more power than the EDU Mini.

With a USB port on one end, and a 20-pin JTAG connector on the other end, just plug in the included cable and connect to your favorite ARM board, or just connect the pins you need, to get started.

Note: This unit is for Educational and Home Hobby Use Only. Please be sure that you agree to these terms before purchasing: Terms of use. If you require commercial use, please check out our related products for other programmers such as the J-Link BASE Compact.

How to program SAMD21 or SAMD51 boards (or other ARM processors).

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    As taronhov said, what is the Hardware Revision/Version of this J-Link EDU? is it that latest (v11) ?

  • PickledDog / about 5 years ago / 1

    Very cool! Happy to see the J-Link's carried here. Do you have any plans to carry a 0.1" to 0.05" adapter?

    • M-Short / about 5 years ago / 2

      We are looking at different options, but haven't settled on anything yet, but we are definitely looking into it.

Works as expected!!!

For anyone who is wondering what hardware version I have got, it's v11 at least what I have got from this site. I don't know why the reviewer above me gave it one star or had issues with it. I have managed to program and debug with it without any problems many ST boards including BluePill board. I think J-Link is an excellent quality product and is worth it's investment

An expensive and so far useless brick

Urgently needed a proper debugger to debug ESP8266. After reading all the reviews, it seemed the J-link should be the right solution for this and future projects.

following all the instructions I burned 3 days trying to get it to debug anything. but this fancy brick wouldn't even talk to a Bluepill board (STM32).

last J-link product I buy.
