FSR400 Force Sensitive Resistor Force Sensor
 
Description:
A small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. 
This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR, its resistance will be larger than 1MΩ, with full pressure applied the resistance will be 2.5kΩ.
Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. 
These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.
Dimensions: 
Overall length: 1.75"
Overall width:  0.28"
Sensing area:  0.3"
Package Included :
1 Pcs FSR400 Force Sensitive Resistor Force Sensor

LilyPad 328 Main Board ATmega328P ATmega328 16M For Uno
 
 
Description:
This is LilyPad - the main board consisting of an ATmega328 with the to 5V.
The latest version of the LilyPad supports automatic reset for even easier programming.
The back side of the LilyPad is now completely flat! We now use a surface mount programming connector to keep the header from poking through.
This version of the LilyPad now uses the new ATmega328 at 8MHz. 0016 supports the Pro Mini 328/8MHz/16MHZ. Use this setting when using this new LilyPad 328.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They\\'re even washable!
Buying Guide!
Note:A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles and also to LLC to help fund continued development of new tools and new IDE features.

Pro Micro ATmega32U4 5V 16MHz Replace ATmega328 for Arduino Pro Mini with 2 Row Pin Header for Leonardo Mini Usb Interface
 
 
 
Description:
The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board.
The USB transceiver inside the 32U4 allows us to add
USB connectivity on-board and do away with bulky external USB interface.
 
This tiny little board does all work for Arduino tricks that you're familiar with:
4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as
hardware serial connections Rx and Tx. Running at 16MHz and 5V,
this board will remind you a lot of your other favorite for Arduino-compatible boards but this little guy can go just about anywhere.
There is a voltage regulator on board so it can accept voltage up to 6V(Blue board)/18V(Black board).
If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
 
This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled.
We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit.
ATMega 32U4 running at 5V/16MHz
Supported under for Arduino IDE v1.0.1
On-Board MINI USB connector for programming
4 x 10-bit ADC pins
12 x Digital I/Os (5 are PWM capable)
Rx and Tx Hardware Serial Connections
Our Smallest for Arduino-Compatible Board Yet!

GY-BME280-3.3 precision altimeter atmospheric pressure BME280 sensor module
Description:
ME-BME280 is a Breakout Board featuring a Bosch Sensortec ME280 Temperature, Humidity & Pressure Sensor. 
The board has selectable I2C address jumper (solder link GS2), I2C pull-up resistors, 7 pin header 2.54mm, and two mounting holes 3.5mm.
Default setting of the board; single power rail Vdd=Vdd_IO (solder link GS1), pull-ups resistors (R2, R3) 10k, protocol selector resistor 0ohm (R1), decoupling capacitors 0.1uF on both power supply pins Vdd & Vdd_IO.
If you connect board to both power rails VDD_IO 1.8V and VDD 3.3V be sure to remove the power rail jumper GS1!
 
BME280 Features
- Package 2.5 mm x 2.5 mm x 0.93 mm metal lid LGA
- Digital interface I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
- Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V
   VDDIO interface voltage range: 1.2 V to 3.6 V
- Current consumption 1.8 uA @ 1 Hz humidity and temperature
   2.8 uA @ 1 Hz pressure and temperature
   3.6 uA @ 1 Hz humidity, pressure and temperature
   0.1 uA in sleep mode
- Operating range -40… 85 C, 0…100 % rel. humidity, 300…1100 hPa- Humidity sensor and pressure sensor can be independently enabled/disabled
 
 
Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!
 
This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter accuracy
 
The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.
 
Package Included:
1 Pcs BME280 sensor module
