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.
