These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.
Battery includes built-in protection against over voltage, over current, and minimum voltage.
Note: Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.
Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector. Check this tutorial for an easy way to remove them safely.

Robust power source under extreme conditions (-25 to 60C)
These two Female Stacking Headers alone are, well, lonely. But pair them with any of our Feather boards and you\'re in business!
What do they do? They stack. Put the headers through your Feather and then you can not only plug them into a solderless breadboard, but you could attach circuitry on top as well
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...
Especially designed for Raspberry Pi / Android Tablet / Android cell phone / Android mini PC and so on. You don\'t have to unplug the cable when you don\'t need to charge for raspberry Pi / Android Tablet / cellphone etc.
This temperature amp; Humidity sensor is a wired version of the DHT21, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but...
The Wireless Charging Module can be applied in electronic equipments in common use for close wireless charging or power supply. Consisted of a transmitter and insulation coil, it could serve as a replacement for the Wireless Power Supply with stable 5V output voltage and maximum 1.2A output current. Its small size and insulation coil is more suitable for...
This 4" / 100mm long flexible uFL 2.4GHz antenna has approx 4DBi gain and a 50O impedance so it will work fantastically with just about any 2.4-2.5GHz wireless receiver/transmitter such as the CC3300 Wifi Breakout !
Miniature Single Pull Single Throw switches. These are high quality Omron type B3F momentary on switches. This switch has a very large 5mm tall button. Perfect as an embedded switch behind an enclosure wall. Rated up to 50mA.
The MQ5 is used in gas leakage detecting equipment in consumer and industry applications,this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes and cigarette smoke. The sensitivity can be adjusted by the potentiometer.
