DescriptionRotary encoders can be used similarly to potentiometers. The difference being that an encoder has full rotation without limits(It just goes round and round). They output gray code so that you can tell how much and in which direction the encoder has been turned. They're great for navigating menu screens and things like that.This encoder is especially cool because it has a common anode RGB LED built in， as well as a push-button. This version has an updated material that is heat resistant and slightly changed dimensions， but should still work well with our rotary encoder breakout board.FeaturesSwitch Travel：0.5mmShaft Diameter：6.0mmShaft Length：18mmVertical Through-Hole Mount24 Pulses per RotationRed/Green/Blue LEDPushbutton

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 great thing about open source is that while SparkFun has designed our own MicroMod carrier boards， that does not stop you from creating your very own MicroMod carrier board. The MicroMod DIY Carrier Kit includes five M.2 connectors(4.2mm height)， screws， and standoffs so that you can get all the special parts you may need to make your own carrier board.MicroMod uses the common M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic 'key' on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the 'E' key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The 'E' key is fairly common so a user could insert a M.2 compatible Wifi module but because the screw mount doesn't align， the user would not be able to secure an incompatible device into a MicroMod carrier board.MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

DescriptionA lot of the time you just need to add more analog inputs to solve a problem. It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project. These channels can be used as single-ended inputs， or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you "zoom in" on a very small change in analog voltage(but will still effect your input range and resolution). Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The ADS1015 uses its own internal voltage reference for measurements， but a ground and 3.3V reference are also available on the pin outs for users. This ADC board includes screw pin terminals on the four channels of input， allowing for solderless connection to voltage sources in your setup. It also has an address jumper that lets you choose one of four unique addresses(0x48， 0x49， 0x4A， 0x4B). With this， you can connect up to four of these on the same I2C bus and have sixteen channels of ADC. The maximum resolution of the converter is 12-bits in differential mode and 11-bits for single-ended inputs. Step sizes range from 125μV per count to 3mV per count depending on the full-scale range(FSR)setting.We have included an onboard 10K trimpot connected to channel A3. This is handy for initial setup testing and can be used as a simple variable input to your project. But don't worry， we added an isolation jumper so you can use channel A3 however you'd like.Note：The I2C address of the ADS1015 is 0x48 and is jumper selectable to 0x49， 0x4A， 0x4B. A multiplexer/Mux is required to communicate to multiple ADS1015 sensors on a single bus. If you need to use more than one ADS1015 sensor consider using the Qwiic Mux Breakout.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.Get Started with the SparkFun Qwiic 12-Bit ADC Hookup GuideFeaturesADS1015Operating Voltage(VDD)：2.0V-5.5V(Note：When powering with a Qwiic cable， the input range is only 3.3v)Operating Temperature：-40℃ to 125℃Operation Modes：Single-Shot， Continuous-Conversion(Default)， and Duty CyclingAnalog Inputs：Measurement Type：Single-Ended(Default)Input Voltage Range：GND to VDDFull Scale Range(FSR)：±.256V to ±6.114V(Default：2.048V)Resolution：12-bit(Differential)or 11-bit(Single-Ended)LSB size：0.125mV - 3mV(Default：1 mV)Sample Rate：128 Hz to 3.3 kHz(Default：1600SPS)Current Consumption(Typical)：150μA-200μAI2C Address：0x48(Default)， 0x49， 0x4A， or 0x4BScrew pin terminals for solderless connection to voltage sourcesFour unique I2C addresses：0x480x490x4A0x4B2x Qwiic connection portsOnboard 10K trimpot
