TSOP56 NOR UNI (TYPE B) ADAPTER
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.
Using a jumper the power source can be switched between using power from the FlashcatUSB xPort to using power from an external power source. At the end of the board you can put pins which you can use to supply power from an external power source, there is also a footprint for a capacitor if you need it for your setup. The capacitor footprint is for a capacitor with 2mm lead spacing, something like this should work.
