It uses the industry-standard 0.100" (2.54 mm) pitch and terminates via through-hole solder tails, making it a direct fit for standard 0.100" grid prototyping boards or production PCBs.
The 34 positions match a 34-conductor ribbon cable or a 34-pin IDC receptacle, so the BOM line count is a straight one-to-one match. The gold or GXT mating finish, at 30 µin, is a production-grade thickness that survives hundreds of mating cycles without wear-through — tin plating at half the thickness would gall after 50 cycles.
