These are 1ft long jumpers with female connectors on both ends. Use these to jumper from any male header on any board, to any other male header. Combine these with our male to male jumpers to create a male to female jumper. Multiple...

This battery clip provides a secure, insulated connection to the terminals of a 9V batter

Standard 'Watch' or Real-Time-Clock crystal. 32.768kHz means it is precisely half of a 16-bit counter. Start counting at 0x8000 (or 32768). When the counter rolls over from 65535 to 0, then you know that exactly one second has passed....
