Description。This is a jumper adapter cable that comes pre-terminated with a female Qwiic JST connector on one end and female connectors on the other. The cable insulation is made from a highly malleable material making it more flexible than our origina

Description。This is a piezoresistive force sensor from Tekscan. The harder you press， the lower the sensor's resistance. Pressing hard， the resistance changes from infinite to ～300k. The sensor itself is thin and flexible， but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor(someone standing)， weight sensor， pressure sensor(impact testing)， etc.。The overall length is about 8.5". Sensor comes with 0.1" spaced， reinforced， breadboard friendly connector.。This sensor comes in three flavors. This sensor ranges from 0 to 25lbs of pressure.

Description。The CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage(VP)and the negative-going voltage(VN)is defined as hysteresis voltage(VH).。Features。Schmitt trigger action with no external components。Hysteresis voltage typ. at 0.9V at VDD = 5V， 2.3V at VDD = 10V， and 3.5V at VDD = 15V。Noise immunity greater than 50%。No limit on input rise and fall times。Standardised， symmetrical output characteristics。100% tested for quiescent current at 20sV。Maximum input current of 1μA at 18 V over full package temperature range； 100nA at 18V and 25℃。Low VDD to VSS current during slow input ramp

Description。This is a 200mm long 4-conductor cable with 1mm JST termination. It's designed to connect Qwiic enabled components together but can be used for other applications as well. The cable insulation is made from a highly malleable material making it more flexible than our original Qwiic cable particularly in tight spaces or enclosures.。Each Qwiic Cable's wires have been color coded to red， black， blue and yellow.。The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.。。Features。Dimensions：200mm(7.87")Length

Description。Keeping your workspace clean and well kept has always been a paramount concern for keeping all your possessions well maintained and pristine. With this Insulated Silicone Soldering Mat， you will be provided with the means to protect your d

。Description。The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell， and with some calibration you'll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale， process control or simple presence detection.。This version of the SparkFun Load Cell Amplifier features a few changes that you specifically asked for! We have separated the analog and digital supply， as well as added a 3.3uH inductor and a 0.1uF filter capacitor for digital supply. Need even more? Checkout the SparkFun Qwiic Scale. It has all the features of the HX711 but with additional library support， a true I2C interface， and no soldering required!。The HX711 uses a two-wire interface(Clock and Data)for communication. Any microcontroller's GPIO pins should work， and numerous libraries have been written， making it easy to read data from the HX711. Check the hookup guide below for more information.。Load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. These are commonly colored RED， BLK， WHT， GRN and YLW. Each color corresponds to the conventional color coding of load cells：Red(Excitation+ or VCC)。Black(Excitation- or GND)。White(Amplifier-， Signal- or Output-)。Green(A+， S+ or O+)。Yellow(Shield)。The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI(electromagnetic interference). Please keep in mind that some load cells might have slight variations in color coding.。Note：Special thanks to Bodge for supplying the Library for the HX711!。Get Started with the HX711 Load Cell Amplifier Guide。Features。Operation Voltage：2.7V--5V。Operation Current：< 1.5mA。Selectable 10SPS or 80SPS output data rate。Simultaneous 50 and 60Hz supply rejection

Description。The SN74HC595N is a simple 8-bit shift register IC. Simply put， this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. Your chosen microprocessor is able to communicate with the The SN74HC595N using serial information then gathers or outputs information in a parallel(multi-pin)format. Essentially it takes 8 bits from the serial input and then outputs them to 8 pins.。This small DIP packaged IC contains an 8-bit， serial-in parallel-out shift register that feeds an 8-bit D-type storage register with parallel 3-state outputs.。Note：。This is a drop-in replacement for the 74HC595 shift register IC and should function just fine in any application the previous version could.。Get started with the Shift Register Guide。Features。8-Bit Serial-In， Parallel-Out Shift。Wide Operating Voltage Range of 2 V to 6 V。High-Current 3-State Outputs Can Drive Up to 15 LSTTL Loads。Low Power Consumption：80-μA。±6-mA Output Drive at 5 V

6V動作で3.2kg・cmのトルクを発生し、標準の3ピンケーブル(赤：電源、茶色：GND、黄色：データ)を備えた小型サーボです。

Arduino Pro Mini328-3.3V/8MHzは最小機能、小型サイズのArduinoボードで8MHzのブートローダー搭載です。マイコンの動作電圧は3.3Vで標準の5Vと異なります。レギュレーターとクロック発振子を搭載しマイコンの最小限の動作は可能ですがUno等フルスペックのArduinoが標準搭載しているUSBインターフェースは省略されFTDIのインターフェースボードを外付けする仕様となっています。オートリセットは外付けインターフェースのDTR端子が有効な場合のみサポートされます。マイコンの電源電圧は3.3Vなのでインターフェースの電圧にも制限があります。メーカーのコメントによれば入門時はUno R3でスタートし習熟したユーザーが仕様を理解した上でこのArduino Proを利用すべし、とあります。("Pro"というネーミングは"初心者お断り"の意味でしょうか…)
