Audio Jack - 3.5mm TRRS (SMD)
This is a 3.5mm TRRS SMD audio jack. TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for “tip, ring, ring, sleeve,” which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players). Documents: Dimensional Drawing ..

Jumper Wires Premium 6
Jumper wires are awesome. Just a little bit of stranded core wire with a nice solid pin connector on either end. They have the flexibility of stranded wire but will fit directly into breadboards and female pin headers. The only downside to the standard jumper wires we carry is that they’re a tad too thin to use for most power applications, so we got some beefy ones! These 20AWG jumper wires work just like our smaller gauge premium jumpers except that they can handle a little more juice. If you’ve ever been unsettled by warm jumper wires, give these a try!

Don’t be caught by surprise next time your board suddenly powers-down! The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much ‘fuel’ is left in the tank. The..
