The clip adapters are all designed to work with the FlashcatUSB xPort made by EmbeddedComputers, on that webpage is a list of the NAND and NOR flashes it supports.
The names of the adapters use the same naming convention as those of the FlashcatUSB Parallel Adapters since they support flashes with the same pinouts, on that webpage you can buy socket versions of all these adapters as well as other socket adapters.
For each clip adapter there is an image of the NAND/NOR pinouts that it supports, so you can figure out which adapter will work with the flash you need to program.
You can download the software for the FlashcatUSB xPort from here.
Here is a video I made about the clip adapters as well as a basic tutorial on using them with the FlashcatUSB xPort. I’ve made a more in depth tutorial video and a video going over some troubleshooting steps. I also have guides here as well.
You can find the clips themselves on websites like eBay, AliExpress, and various modchip/modding websites. I’ve included links to some websites that sell the clips on each product listing, however I’ve never bought clips from them myself.
