Description。USB-C is fantastic. What makes this cable even better is that one of the features we love so much about USB-C has been replicated to the USB-A 2.0 plug! 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. If you're looking for a the full USB-C implementation checkout our USB 3.1 cable.。Features。Reversible USB-A connector。Reversible USB-C connector

。Description。Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer(e.g. Flash， Processing， MaxMSP). The open-source IDE can be downloaded for free(currently for Mac OS X， Windows， and Linux).。The Arduino Mega is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins(of which 14 can be used as PWM outputs)， 16 analog inputs， 4 UARTs(hardware serial ports)， a 16 MHz crystal oscillator， a USB connection， a power jack， an ICSP header， and a reset button. It contains everything needed to support the microcontroller； simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.。Never fear for accidental electrical discharge， either since since the Mega also includes a plastic base plate to protect it!。The Mega 2560 R3 also adds SDA and SCL pins next to the AREF.。In addition， there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board.。The other is a not connected and is reserved for future purposes.。The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.。Not sure which Arduino or Arduino-compatible board is right for you?

。Description。The 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." Check the Documents tab above for more information.。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.。The TMP117 High Precision Temperature Sensor can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!。Need a custom board? This component can be found in SparkFun's A La Carte board builder.

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。If you're looking for a fully-featured Raspberry Pi 4 case， then look no further than the Argon ONE Pi 4 Raspberry Pi Case. In addition to providing passive and active cooling to keep the Pi 4 running cool， it incorporates multiple pieces to allow for access to different levels of the board like a magnetic dedicated door for the 40 pin connector that provides pin numbers and labels. An included fan HAT provides software controllable， active cooling while the aluminum enclosure provides passive cooling through two extrusions that provide a heat sink for the ICs on board(thermal tape included). An additional interface board plugs into the Pi and redirects all the connectors(outside of the 40 pin)to the one side of the enclosure. But probably the best feature is a properly configured power button that provides the ability to safely shutdown， reboot， or force shutdown the Pi.。Features。Passive and active Cooling。All connectors positioned to one side of the enclosure。Magnetic door provides access to the 40 pin header without exposing the board。Aluminum enclosure with plastic base。Power button for safe power cycling

。Description。The SparkFun Continuous Rotation(CR)Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state， the CR Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the CR Servo Trigger， you simply connect a hobby servo and a switch， then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servo in your projects without having to do any programming!。When we introduced the original Servo Trigger， we mentioned that it could be reprogrammed to be more useful with continuous rotation servo motors. But reprogramming the firmware is somewhat tedious， and users asked for a Servo Trigger preprogrammed with the continuous rotation logic. With this little board you will be provided an easy way to deploy continuous rotation servos into your projects!。The heart of the CR Servo Trigger is an Atmel ATtiny84 microcontroller， running a small program that implements the servo control features designed for continuous rotation servos. On board each of these CR Servo Triggers you will find three potentiometers："A" sets the position the servo sits in while the switch is open， "B" sets the position the servo moves to when the switch is closed， and "T" sets the time it takes to get from A to B and back.。Compared with a servo motor， the CR Servo Trigger board draws very little current， roughly 5mA at 5V. Be sure to note that if you're using the CR Servo Trigger to control your motor， the absolute maximum supply voltage that should be applied is 5.5 VDC. Additionally， the SparkFun CR Servo Trigger is designed to make it easy to daisy chain boards - you can simply connect the VCC and GND pads on adjacent boards to each other.。Note：This idea originally came from our friend in the Oakland area， CTP.
