10-pin Needle Adapter

SEGGER offers the 10-pin Needle Adapter, which has been designed to connect Flasher 5, Flasher 5 PRO, Flasher ST7 or Flasher STM8 to a PCB which does not come with a mating connector or programming header. The designed pattern with 3 locating pins ensures that the adapter can only be connected in one way.

The 10-pin needle adapter allows manufacturers to save costs and space on their PCBs since there is no need to provide the PCB with additional connectors. It adapts from the 10-pin, 0.1 inch connector to a 10-pin, 0.05 inch needle pattern.
