Frequently asked questions
Is this header compatible with 2.54 mm breadboards?
No. Breadboards use a 2.54 mm pitch, so a 2 mm header will not line up with their holes. Use a 2.54 mm header for breadboard work.
How do I connect a 2 mm module to this header?
Insert the module's 2 mm male pins into the socket. Check the pin count and orientation before inserting so the module lines up with the correct pins.
