- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA2094:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged.

## Description

This adapter board is designed for adapting a 'classic' 2x10 (0.1"/2.54mm pitch) JTAG cable to a slimmer 2x5 (0.05"/1.27mm pitch) SWD Cable. It's helpful for using products like the [JTAGulator](https://core-electronics.com.au/jtagulator-by-grand-idea-studio.html) or [SEGGER J-Link](https://core-electronics.com.au/segger-j-link-edu-jtag-swd-debugger.html) with tiny boards that use the 10-pin SWD programming connector.

This board comes with no cables. It's really just the adapter - but is super helpful when you want to use JTAG debugging on boards that can't support 2x10 cables. [We do stock the SWD cable if you need one here!](https://core-electronics.com.au/10-pin-2x5-socket-socket-1-27mm-idc-swd-cable-150mm-long.html)
