SmartWheels JTAG Adapter | 20 Pin 2.54mm to 10 Pin 1.27mm Converter with 10 Pin 1.27mm FPC Cable

UBYTE–SmartWheels JTAG Adapter

A Simple and Reliable Bridge Between 20-Pin and 10-Pin JTAG

Interfaces

The UBYTE–SmartWheels JTAG Adapter converts the standard 20-pin 2.54 mm JTAG

header into the smaller 10-pin 1.27 mm connector found on many modern ARM Cortex-M

boards. This allows you to connect traditional debugging tools to compact hardware without

compatibility issues.

Built for Everyday Use

● Standard Compliant – Uses the official ARM JTAG/SWD pinout to guarantee correct

signal mapping and stable connections.

● Tool Friendly – Compatible with widely used debuggers such as Segger J-LINK, ARM-

USB-OCD, ARM-USB-TINY, and many more.

● Compact & Practical – Small board size with M3 mounting holes makes it easy to fix

securely in enclosures, test rigs, or development setups.

Safe and User-Focused Design

● ESD Protection Ring – The board includes a protective ESD guard ring. This feature

directs static electricity safely to ground instead of sensitive signal lines, making the

adapter safer to handle by hand during development.

● Cable Included – Each adapter ships with a 20 cm 10-pin 1.27 mm JTAG ribbon

cable, so you can start working immediately without hunting for the right accessories.
