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。Poke Home Connectors have been featured on a number of our boards over the last few years by providing a simple screw-terminal-type connector for easy wire connection purposes. Similar to screw terminals， Poke Home Connectors grasp a wire entered into the receiving area of the pin-out by pressing down on the small plastic strip at the end of the housing. Doing so raises the internal clamp and， upon release of the button secures the wire in place without any soldering required.。Poke Home Connectors work better in environments with a lot of vibrations(i.e. automotive applications)or when a wire is expanding or contracting due to temperature cycling. Additionally， the tension in the connector is automatically adjusted to the wire gauge(assuming it is within the accepted wire thickness)as opposed to variances in tension when a user tightens the screw terminal.

Description。This is the FemtoBuck， a small-size single-output constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This board is based off of the PicoBuck LED Driver， developed in collaboration with Ethan Zonca， except instead of blending three different LEDs on three different channels the FemtoBuck controls just one.。For the FemtoBuck， we've increased the voltage ratings on the parts to allow the input voltage to cover the full 36V range of the AL8805 driver. Since the FemtoBuck is a constant current driver， the current drawn from the supply will drop as supply voltage rises. In general， efficiency of the FemtoBuck is around 95%， depending on the input voltage. On board each FemtoBuck you will find two inputs for both power input and dimming control pins and an area to install a 3.5mm screw terminal. Finally at either side of the board you will find small indents or "ears" which will allow you to use a zip tie to secure the wires to the board after soldering them down. This version of the FemtoBuck is equipped with a small solder jumper that can be closed with a glob of solder to double the output current from 330mA to 660mA.

Description。The SparkFun TSH82 Configurable OpAmp Board was designed to give you the best combination of performance and flexibility that we could achieve by giving you two gain stages， each one independently accessible on the header pins. Each stage is natively configured as an inverting amplifier that can also be strung together to expand the capabilities of the TSH82 from STMicroelectronics. With the use of the jumpers on the back of the board， you can configure each stage for non-inverting operation， differential input， and DC input coupling.。Electrically speaking， both stages on this board are identical. The default configuration is inverting with a gain of -4.7 with a bandwidth of almost 10MHz. Input signals are AC coupled， possess an input impedance of 10K with a low frequency cutoff of 15.9Hz. Outputs are also DC coupled， so don't forget to add a capacitor to the output if you're running a single-ended supply and need to strip out the DC component. The board will also operate with a single-ended DC power supply of 4.5V to 12V， or a bipolar supply from +/-2.25V to +/-6V.。On the back of the board you'll find 10 solder jumpers that can be used to change the board's performance， but nothing there needs to be changed to use it in it's default state.。Get Started With the Configurable OpAmp Board 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。This single disc load cell(sometimes called a strain gauge)can translate up to 50kg of pressure(force)into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to， and proportional of， the strain(e.g. pressure or force)applied to the disc. With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.。Disc load cells are a bit easier to mount than bar-style load cells， making them more straightforward to implement into a design.。Each load cell is made from an steel-alloy and is capable of reading a capacity of 50kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = E+， green = O+， black = E-， and white = O-. Additionally， these load cells offer an IP66 protection rating.。Get Started with the Load Cell Guide。Features。20mm×11mm， 2000mm Wire

Built upon the same foundation as our 3.3V SparkFun FTDI Basic Breakout， the Beefy 3 is equipped with an AP2112K voltage regulator making this FTDI basic breakout board capable of handling a current load of up to 600 mA! With the addition of a more "Beefy" voltage regulator your will now be able to power a 3.3V project directly from the FTDI. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.。This board 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 pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND， green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.。There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working， however this board now requires a Micro-B USB cable. The FTDI Cable is well protected against the elements， but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.。This board was designed to decrease the cost of Arduino development and increase ease of use(the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.

Description。Your 5V system can wield great power with this big， beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!。The heart of the board is sealed， SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor， and an LED tells you when the relay is closed. This is kit， so it comes as through-hole parts with assembly required， which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.。There are some pretty beefy traces connecting the relay to the load pins， but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load， you'll need to solder directly to the board. As always with high current and voltage， play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time， but in an enclosed area heat can build up.。Note：Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage， please check out the IoT Power Relay. The IoT Power Relay is fully enclosed， making it lot safer.。Get Started With the Beefcake Hookup Assembly Guide。Features。Voltage Rating：220VAC/28VDC。VCC requirements：4-6V， 150mA capable。SPDT pins exposed(Form C)。14 AWG screw terminals for relay connections.。10 AWG solder lugs for relay connections.。Flyback diode included。Zener recovery diode included(decreases turn-off time)。Heavy oz. copper on PCB
