With this breadboard and another similar one for the full size connector you're free to map the signal however you need them. Premade adapter boards containing both size connectors only provide one fixed mapping which didn't suit my needs. Review: Good enough for my purposes. - I bought this little adapter board to use with a very common display module that Arduino enthusiasts play around with. (The JY-LKM1638 F71A 8 Digital Tube + 8 Key + 8 Double Color LED Module ). The board has two JTAG connectors for inputs and outputs and comes with a ribbon cable with the JTAG plug on both ends. I wanted a breakout module where I could plug in the other end of the ribbon cable and wire the connections to my Arduino circuit. This module provides that capability. The solution is not perfect. This module was obviously made for some specific application because the printed pin labels don’t match the functions of my display board connector. Also, when I plug in the included ribbon cable, the red wire is not on my pin1, but rather on pin 10. Neither is a deal breaker, because once I wire up my circuit I wont be reading the silk screened labels on the board and the key on the cable connector only lets you plug it in one way. No problems like those mentioned by others.

Boundary scan can access the signal logic state inside the chip, the state of the chip pins, etc. - The distance between the holes in the adapter board is 2.54mm, and the data transmission line is a 10-pin ribbon cable - This board allows the use of ADA1675 cables to connect Atmel-ICE PCBA and your components to debug Atmel ATmega and Atmel Arm in the Atmel studio environment. - Used in most Atmel AVR JTAG debuggers, system programmers, Isp downloads, Segger's JLINK and other JTAG/SWD programmers/debuggers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09JKBMPKZ | | Brand | Treedix | | Color | Grey | | Colour | Grey | | Compatible Devices | ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, ARM-USB-TINY-H, ADA1675 cables, Atmel-ICE PCBA, Segger’s JLINK | | Compatible devices | ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, ARM-USB-TINY-H, ADA1675 cables, Atmel-ICE PCBA, Segger’s JLINK Compatible devices ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, ARM-USB-TINY-H, ADA1675 cables, Atmel-ICE PCBA, Segger’s JLINK See more | | Connector Type | Usb | | Connector type | Usb | | Customer Reviews | 4.2 out of 5 stars 10 Reviews | | Item Weight | 0.03 Kilograms | | Item weight | 0.03 Kilograms | | Manufacturer | Treedix | | Model Number | Treedix | | Number of Items | 2 | | Number of Ports | 10 | | Number of ports | 10 | | Package Quantity | 1 | | UPC | 764784798620 | ## Product Details - **Brand:** Treedix - **Colour:** Grey - **Connector type:** Usb - **Item weight:** 0.03 Kilograms ## Images ![Treedix 2pcs JTAG Breakout Board Adapter SWD Adapter Board Jtag Debug Board with 2 Row 2.54mm Pitch 10pins Female to Female IDC Connector Flat Flexible Gray Ribbon Jumper Cable 200mm Pitch for J-Link - Image 1](https://m.media-amazon.com/images/I/512FjaSt8iL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value and very useful to map JTAG signals. *by C***Y on 11 September 2025* Well made and extremely useful to adapt wiring between full size and this small size JTAG connector cable.

While electrically it would probably work, it had a couple of mechanical issues for my application and probably yours. I intended to solder on some standard breadboarding pins that I've use with other boards (e.g. from adafruit) and plug it into my standard breadboard. I specifically bought the 0.1" spacing board for this intent. The pin-to-pin spacing isn't an issue, but the spacing between the two banks of holes is not a multiple of 0.1" and won't fit in the breadboard ... couldn't even bend the pins a little. Also, more minor issue is that the labelling was for SPI, not JTAG. Finally, and even yet more minor, the way the ribbon cable is crimped, it covers up most of the labels anyway. So, I could make it work, but in the end, I just resorted to breadboard jumper cables to make my connections. ## Frequently Bought Together - Treedix 2pcs JTAG Breakout Board Adapter SWD Adapter Board Jtag Debug Board with 2 Row 2.54mm Pitch 10pins Female to Female IDC Connector Flat Flexible Gray Ribbon Jumper Cable 200mm Pitch for J-Link - MG Chemicals 8341 No Clean Flux Paste, 10 ml Pneumatic Dispenser (Complete with Plunger & Dispensing Tip) - DSD TECH SH-U09C5 USB to TTL UART Converter Cable with FTDI Chip Support 5V 3.3V 2.5V 1.8V TTL 0.33FT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/378938972-treedix-2pcs-jtag-breakout-board-adapter-swd-adapter-board-jtag](https://www.desertcart.sk/products/378938972-treedix-2pcs-jtag-breakout-board-adapter-swd-adapter-board-jtag) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-14*
