This is a 1.5' long USB extension cable equipped with type A male connector on one end to plug into your computer and a type A female connector at the other that allows for a second USB cable to be inserted. This cable is perfect for adding a periphery that utilizes USB without having it plugged directly into your computer while not cluttering your work area with its excess length. We use this cable a lot with MicroViews, RFduinos, and USB Breakouts.

This is a USB 2.0 type A to Micro-B 5-pin black cable. You know, the mini-B connector that usually comes with cell phones, Cameras, MP3 players, etc. We specifically like these 6" long cables because using USB peripherals in projects within a small enclosure is much easier these days, and most times you really don't need six feet of cable to do that. You can still use this USB cable with our Micro-USB LiPo Charger Basic, Pro Micros, Micro-B USB breakout, or anything else that utilizes a...

USB Weather Board Description: Got weather? This board can handle it. The USB Weather Board includes onboard sensors for barometric pressure, humidity, temperature, and light level. We've also added headers in the new version so you can connect the board to our weather meters (not included), adding sensors for wind speed, wind direction, and rainfall. You can send all this data to a computer or datalogger via mini-USB cable, TTL serial (3.3V), or wirelessly...

A vibration motor! This itty-bitty, shaftless vibratory motor is perfect for non-audible indicators. Use in any number of applications to indicate to the wearer when a status has changed. All moving parts are protected within the housing. With a 2-3.6V operating range, these units shake crazily at 3V. Once anchored to a PCB or within a pocket, the unit vibrates softly but noticeably. This high quality unit comes with a 3M adhesive backing and reinforced connection wires. Documents: Datasheet ...
