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!

DescriptionThe PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default， each channel is driven at 330mA； that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board， allowing it to be used up to the full 36V rating of the AL8805 part.Three signal inputs are provided for dimming control. You can use the PWM signal from an Arduino or your favorite microcontroller to dim each channel individually， or you can tie them all to the same PWM for simultaneous dimming. Dimming can be done by an analog voltage(20%-100% of max current by varying voltage from .5V-2.5V)or by PWM(so long as PWM minimum voltage is less than .4V and maximum voltage is more than 2.4V)for a full 0-100% range. A small jumper is provided for each channel to allow you to increase the drive strength from 330mA to 660mA. Two mounting holes for 4-40 or M3 screws are provided on either side of the board. They are perforated so they can be easily snapped off with a pair of pliers， if a smaller footprint is desired.Note：If you're going to use screw terminals， this board uses two different sizes. Check the related products for both sizes you'll need.Note：The PicoBuck LED Driver was made in collaboration with Ethan Zonca. A portion of each sale is given back to him.

These cables have minor， yet genius modifications that allow them to be plugged into their ports regardless of orientation. No longer will you fight the USB "super position" where both orientations of your plug seem incorrect. A simple solution to a problem that nearly everyone has faced.Until we have converted all our hubs， chargers， and ports over to USB-C this is the cable you're going to need for basic USB 2.0 connections. This cable is much thinner and flexible than its 3.1 counterpart and is perfect for USB to serial applications as well as for direct connection to basic microcontrollers.This cable has the D+/D- wires along side large-gauge VBUS/GND wires. Rated for 2A， we've successfully pulled 2A@5V with minimal voltage drop.

DescriptionWe all like to know the temperature， right? Well， with the SparkFun TMP102 Digital Temperature Sensor， we've made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout TMP102， we've added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However， we still have broken out 0.1"-spaced pins in case you prefer to use breadboard.The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature， the TMP102 uses the I2C bus of the Arduino to communicate the temperature.The TMP102 is capable of reading temperatures to resolution of 0.0625℃， and is accurate up to 0.5℃. The breakout has built-in 4.7kΩ pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling， so there is no need to use level shifting.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 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 Qwiic TMP102 Digital Temperature Sensor GuideFeaturesUses the I2C interfaceI2C Address：0x48 by default(Three additional addresses available， as well)12-bit， 0.0625℃ resolutionTypical temperature accuracy of ±0.5℃3.3V sensorSupports up to four TMP102 sensors on the I2C bus at time2x Qwiic Connectors

DescriptionThis is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins， this cable is a perfect candidate for powering， connecting， and accessing the login and debug console on an older-version Raspberry Pi.The FTDI cable is designed around an FT232， which is housed in a USB-A connector. The other side of the cable is terminated with a separated 4-pin connector with the following pinout：RX(Yellow)， TX(Orange)， VCC(5V)(Red)， and GND(Black). A link to the FTDI drivers can be found in theDocumentssection above.Note：Please be aware that while the I/O pins in this cableoperate at 3.3V， the VCC pin is 5V. The VCC pin is NOT 3.3V like theI/O pins.

DescriptionThe SparkFun Qwiic TMP117 breakout is a high precision temperature sensor equipped with an I2C interface. It outputs temperature readings with high precision of ±0.1℃ across the temperature range of -20℃ to +50℃s with no calibration and a maximum range from -55℃ to 150℃. The SparkFun High Precision Temperature Sensor also has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. 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 SparkFun High Precision Temperature Sensor also includes programmable temperature limits， and digital offset for system correction. While the TMP102 is capable of reading temperatures to a resolution of 0.0625℃ and is accurate up to 0.5℃， the on-board TMP117 is not only more precise but has a 16-bit resolution of 0.0078℃!To make this breakout even easier to use， we've written an Arduino library to help you get started "Qwiic-ly."

DescriptionThe SparkFun Qwiic Dual Solid State Relay is a power delivery board that allows users to switch two AC loads from a low power microcontroller using the SparkFun Qwiic connect system. The board features two 25A/250VAC solid state relays that utilize the Zero Cross Trigger method so you can toggle two loads on a 60Hz AC carrier signal on and off up to 120 times per second!An ATTiny84 acts as the "brain" of the SparkFun Qwiic Dual Solid Relay to accept I2C commands to toggle the two relays as well as a few other special commands. The I2C address of the ATtiny84A is software configurable so， if you have a seriously big power project in mind， you could daisy chain over 100 Qwiic Dual Solid State Relays.Messing with such high voltage is dangerous! We've included many safety precautions onto the PCB including ground isolation between the relay and other circuitry and a milled out area isolating each side of AC. However， with all the safety precautions included with the SparkFun Qwiic Dual Solid State Relay， this is still a power accessory for users who are experienced around， and knowledgeable about high AC voltage. If you're not comfortable with handling AC voltage in this way， you may want to check out the IoT Power Relay instead.Note：The relays are rated for a max of 25A with forced air cooling. If you do not have forced air cooling， 10A max through the relays is recommended.The SparkFun Qwiic connect system is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error.
