“It does just what it needs to and it's a good price.
I use it to adapt a ST Link v3 to older dev boards, but hard to cut away the shroud on the smaller connector. So I think going with a connector without a shroud would make it more versatile. Knocking a star off for that.”
“This adapter board is ideal and very useful if you use a Segger J-LINK or similar for debugging, as it provides an interface that enables you to interface the 20-Pin 2.54mm IDC header to the 10-Pin 1.27mm headers as found on most development boards. A word of warning be careful if you buy a 1.27mm male header socket to fit on boards that have the through hole connections but not already fitted with the socket, there are a number of 1.27mm headers advertised that unfortunately although the Pins in each column are spaced at 1.27mm they have a 2.54mm spacing between the 2 rows of pins. These obviously will not fit on the board nor permit connections to the 10-Pin cable plug.”
