。Description。The MAX31820 ambient temperature sensor provides 9-bit to 12-bit Celsius temperature measurements with ±0.5℃ accuracy over a +10℃ to +45℃ temperature range. Over its entire -55℃ to +125℃ operating range， the device has ±2.0℃ accuracy.。The device communicates over a one-wire bus that， by definition， requires only one data line(and ground)for communication with a central microprocessor. In addition， the device can derive power directly from the data line， eliminating the need for an external power supply. Requiring so few pins enables the device to be placed in a 3-pin TO-92 package. The form factor of this package allows the device to be placed above the board and thus measure the ambient temperature of a system， as opposed to the board temperature that a surface-mount package would measure.。Each MAX31820 has a unique 64-bit serial code， which allows multiple MAX31820 devices to function on the same one-wire bus. Therefore， it is simple to use one microprocessor to control many devices distributed over a large area.。Features。Unique one-wire interface requires only one port pin for communication。Each device has a unique 64-bit serial code stored in onboard ROM。Multidrop capability simplifies distributed temperature-sensing applications。Requires no external components。Can be powered from data line； 3.0V to 3.7V power-supply range。Measures temperatures from -55℃ to +125℃。±0.5℃ accuracy from +10℃ to +45℃。Thermometer resolution is user-selectable from 9 bits to 12 bits。Converts temperature to 12-bit digital word in 750ms(Max)。User-definable nonvolatile(NV)alarm settings。Alarm search command identifies and addresses devices whose temperature is outside programmed limits(Temperature Alarm Condition)。Available in 3-pin TO-92 package。TO-92 package allows measurement of ambient temperature。Software compatible with the DS1822 and DS18B20

Description。The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution， SPI-compatible， serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals， connecting them at the two ends， and making a temperature gradient between one end and the other(a 'hot' end and a 'cold' one). Once this is achieved， a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end， digitizes the temperature measured and sends that data out the other end via a SPI interface， thereby interpreting the data and translating it for you to read!。With the SparkFun Thermocouple Breakout， the thermocouple's hot junction can be read from -200℃ to +700℃ with an accuracy of ±2℃ while the cold junction， inside the MAX31855K， can only range from -20℃ to +85℃ while maintaining ±2℃ accuracy. The MAX31855K constantly measures the temperature of the cold junction using an internal temperature-sensing diode. The MAX31855K requires a power source from +3.0V to +3.6V(+3.0V nominal)and only draws 1.5mA maximum.。The Thermocouple Breakout is designed to accept a standard thermocouple connector， for convenience and compatibility with probes you may already own. These connectors aren't necessary， and you could solder a thermocouple directly into the through-holes labeled '+' and '-'. If you decide to solder the thermocouple directly to the breakout board， it is recommended that the thermocouple be mounted for strain relief to avoid breaking the thin wires. Notches for a zip-tie or wire wrapping have been provided in the PCB opposite the header for this purpose.。Features。14-bit Resolution。SPI-Compatible， Serial Interface。-200℃ to +700℃ Temperature Reading with ±2℃ Accuracy。3.0V to 3.6V(+3.0V nominal)Required。Accepts Type-K Thermocouple

Description。The Si7021 is a low-cost， easy-to-use， highly accurate， digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for build a weather stations or humidor control system. All you need are two lines for I2C communication， and you'll have relative humidity readings and very accurate temperature readings as a bonus!。There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC， one for GND， and two data lines for I2C communication. This breakout board has built-in 4.7KΩ pullup resistors for I2C communications. If you're hooking up multiple I2C devices on the same bus， you may want to disable these resistors.。Features。0.6"×0.6"

Description。The Teensy 4.1 is one of the most advanced and reliable development platforms on the market today. One of the biggest asks for the board is the ability to connect the 4.1 to the Internet via Ethernet. Luckily， with all the parts included in this kit(as well as a little bit of soldering)， you'll be able to easily add Ethernet functionality to your Teensy 4.1.。The Ethernet Kit for Teensy 4.1 from PJRC includes an Ethernet MagJack connector， a bare circuit board， one ribbon cable， two headers， and a capacitor. As this is a kit that require assembly， some beginner-level soldering is required.。Note：Please be aware that a Teensy 4.1 is。NOT。included with this kit and will need to be purchased separately.

。Description。The LilyPad E-Sewing ProtoSnap is a great way to explore how buttons and switches behave in simple e-sewing circuits before crafting your project. Like other LilyPad ProtoSnap series boards， the individual pieces of the board are pre-wired --- allowing you to try out the function of the circuit before sewing. There is no programming required to use this ProtoSnap， and it can be used right away!。The E-Sewing ProtoSnap includes three white LilyPad LEDs：two connected to a LilyPad Slide Switch and one connected to a LilyPad Button Board. A LilyPad Coin Cell Battery Holder with a CR2032 coin cell battery provides all the power you need for the circuit. All you need to do is design how you want your project to be laid out， and then snap everything apart!。Note：。A portion of this sale is given back to Dr. Leah Buechley for continued development and education in e-textiles.。Note：。Due to the requirements of shipping the included battery， orders may take longer to process and therefore do not qualify for same-day shipping. Additionally， these batteries cannot be shipped via Ground or Economy methods to Alaska or Hawaii. Sorry for any inconvenience this may cause.。Get Started with the LilyPad E-Sewing ProtoSnap Guide

Description。Introducing the SparkFun FT231X Breakout board， complete with the full UART hardware handshake feature! The pin-out of this board matches the FTDI cable to work with official Arduino and cloned Arduino boards. It can also be used for general serial applications.。This board still brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto-reset any Arduino board that has the reset pin brought out to a 6-pin connector.。The coolest thing about the FT231X Breakout is that we have broken out ALL the pins for your use， making this board all the more hackable! It also uses a common microUSB jack.。One of the features of this board is a jumper on the back， which allows the VCC output to be configured to either 3.3V or 5V. This board ships default to 5V， but you can cut the default trace and add a solder jumper if you need to switch to 3.3V. It should be noted that the max input of the FT231X is only 3.3V， but it can operate down to 1.8V with external pull-ups and is also 5V tolerant.

Description。The Xcelite 8-in-1 Screwdriver Set provides eight high-quality bits in a single ergonomic tool. Each bit is easily accessible with a spring-loaded magnetic housing that holds the seven included bits you aren't currently using. Though the screwdriver set includes eight unique bits， the end of the shaft features a 0.25" hex driver that can fit most of your existing 1/4" bits. With a strong magnetic hold and no-roll handle design， this is one of the best all-in-one tools we have used!。The shaft of this multiple-tip driver is made from a chrome-molybdenum vanadium steel that makes for great durability and longevity.
