MAX31865 RTD platinum resistance temperature detector module PT100 to PT1000

LilyPad Coin Cell Battery Holder CR2032
Description:Sure, your flashing, chip-tune playing t-shirt is really cool at the party... but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you've even sewn a LilyPad slide switch in-line. Wouldn't it be nice if there was just a switchonthe battery? Well look no further.
This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it's not easy to accidentally turn off or on.
Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.
Note:A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

Product Description
1. The AMG8833 infrared camera sensor is an 8x8 infrared thermal sensor array. When connected to your microcontroller (or Raspberry Pi), it will return a set of 64 individual infrared temperature readings via I2C. It's like those fancy thermal cameras, but it's compact and simple and easy to integrate. The AMG8833 offers higher performance than the previous AMG8831. The sensor only supports I2C and has a configurable interrupt pin that can be triggered when any single pixel is above or below your set threshold.
2. It can detect humans from a distance of up to 7 meters (23) feet. It is a perfect fit for creating your own human detector or mini camera. We use this breakthrough code on or compatible (sensor communicates via I2C) or on Python's Raspberry Pi. On the Pi, thanks to the image processing help of the SciPy python library, we can insert an 8x8 grid and get some very good results!

1. Volume: 23 * 24MM weight:0.45 g
2. Excellent noise suppression. in the absence of contact input audio, you will not hear any noise even put your ear close to the speaker
3. The two-channel stereo, 5V power supply can output 5W 5W power, directly drive 4, 8 speakers, output power, full of energy, good sound quality, with left and right channel volume adjustment.
4.unique non-LC filter Class-D digital power board, it can be used directly for the USB-powered from computers.
5. dual-panel wiring and proper solution to potential balance and channel crosstalk caused by the wiring between
6. ultra-miniature design, it can easily be placed in a small space inside a variety of digital products, high amplification efficiency.
7. Solder by machine
8. The rated working voltage 2.5-5V, limit operating voltage 5.5V

Description: This is a breakout board for Freescale's MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs. There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin, make sure) you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10K pull-up resistors. If you don't require the pull-up resistors you can open the jumpers by cutting the trace connecting them. There is no regulation on the board, so the voltage supplied should be between 2.5 to 3.6VDC. The VREG pin 2.5 and is connected through a 0.1uF capacitor to ground, which means, unless you modify the board, you can't operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).
