DescriptionThe 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 GuideFeatures8-Bit Serial-In， Parallel-Out ShiftWide Operating Voltage Range of 2 V to 6 VHigh-Current 3-State Outputs Can Drive Up to 15 LSTTL LoadsLow Power Consumption：80-μA±6-mA Output Drive at 5 V

DescriptionSometimes we want our projects on， but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming minimal power(approximately 35nA)and turn your project on after a set amount of time. When you are done polling your sensors， posting data to the web， writing to your logger， or planning world domination， your microcontroller can tell the Nano Power Timer to turn off the power. No more running your microcontroller all day when you only want to read the ambient temperature once per hour.The TPL5110 delay is configured with the use of resistors. We've added a six-way DIP switch to select one of the five preinstalled resistors. The sixth switch is attached to a pad to add your own PTH(or SMD)resistor. The delays associated with the preinstalled headers are shown on the bottom of the board for quick setup. Additionally， you can select more than one switch to combine the resistors in parallel(up to 26 options not including the custom resistor)， check out the hookup guide for a nice chart as to the total resistance and corresponding delay for each combination.The Nano Power Timer can handle voltages between 1.8V and 5.5V as well as current up to 1.1A with times from 100ms to two hours(preconfigured settings range from 30s to 2h). You will find a button on the board which will allow you a quick override to the delay so you can turn your project on whenever you like.Get Started with the SparkFun Nano Power SwitchFeaturesSupply Voltage：1.8V to 5.5VCurrent consumption at 2.5V：35nA Typical(50nA Max)Selectable Time intervals：100ms to 7200s(2 hours)Timer Accuracy：1%

DescriptionThe 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 GuideFeaturesOperation Voltage：2.7V--5VOperation Current：< 1.5mASelectable 10SPS or 80SPS output data rateSimultaneous 50 and 60Hz supply rejection

DescriptionThe Mountable MI：pro is a simple and compact protective case for the micro：bit. This case has been specifically designed with portability and expansion in mind and is compatible with both the original micro：bit V1 and the micro：bit V2. These cases feature a three-layer construction style with ability to wall-mount the whole assembly onto any surface you want while still providing access to all buttons and ports on the micro：bit.
