Description。The Raspberry Pi Zero Case has been designed to fit both the Pi Zero and the Pi Zero W. These official cases consist of several parts and protect the Raspberry Pi Zero from things like rogue wires that might short it out while still allowing full access to the board. Simply snap the RPi into the bottom half of the enclosure， then snap on a desired top. No tools required!。Each case has a standard base featuring a cut-out to allow access to the GPIO， and a choice of three lids：a standard lid， a GPIO lid(allowing access to the GPIO pins from above)and a camera lid(which， when used with the short camera cable supplied， allows the Raspberry Pi camera to be fitted neatly inside it). Additionally， each case includes a 4cm long CSI cable and four rubber feet.。Note：This case does。NOT。include a Raspberry Pi or Camera Module.

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。Get with the times， already! This SparkFun Real Time Clock(RTC)Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power(running at only about 22nA in its lowest power setting)so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the "battery." To make it even easier to get your readings， all communication is enacted exclusively via I2C， utilizing our handy Qwiic system so 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.。This RTC module's built in RV-1805 has not one， but two internal oscillators：a 32.768kHz tuning fork crystal and a low power RC based oscillator and can automatically switch between the two using the more precise crystal to correct the RC oscillator every few minutes. This feature allows the module to maintain a very accurate date and time with the worst case being +/- about three minutes over a year. The RV-1805 also has a built in trickle charger so as soon as the RTC is connected to power the it will be fully charged in under 10 minutes and has the ability to switch power to other systems allowing it to directly turn on or off a power hungry device such as a microcontroller or RF engine.。There is also the option to add a battery to the board if the supercapacitor just isn't going keep your project powered long enough(keep in mind， the supercap can hypothetically make the board keep time for around 35 days)， you can solder on an external battery. That means you can let board sit with no power or connection to the outside world and the current hour/minute/second/date will be maintained.。Note：。The I2C address of the RV-1805 is 0x69 and is hardware defined. A multiplexer/Mux is required to communicate to multiple RV-1805 sensors on a single bus. If you need to use more than one RV-1805 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.

Description。This tri-band GNSS antenna is ideal for GPS L1， GLONASS L1， and Beidou B2 reception. At 45x45mm it is a。large。ceramic antenna with an incredible 38dB LNA gain.。This antenna works well with the GPS-RTK providing reception of Beidou satellites where other more basic GPS antennas cannot. We've chosen to have the antenna manufactured without an enclosure to decrease the weight(45g including cable)making this antenna more ideal for rover and quad-copter applications. Additionally， the cable length has been reduced to 1m to reduce weight and to make a more clean installation.。We recommend this antenna for RTK use when combined with the ground plate. This antenna is ideal for advanced raw， RTK， and post-processed measurements of GPS， GLONASS， and Beidou constellations. If all you need is GPS and GLONASS(basic GNSS)consider our lower cost magnetic mount GNSS antenna.。Antenna is terminated with a standard SMA connector.

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。The PQ12 series of micro linear actuators are ideal for applications requiring precise positioning and compact size. Weighing in at just 22 grams， the PQ12 is incredibly light as well as compact. The affordably-priced PQ12 is the most powerful actuator of it's size. This is why it has become a popular choice for OEM manufacturers as well as Arduino and RC hobbyists. Some industries where the PQ12 are in use include：prosthetics， robotics， medical， simulation.。The PQ12-R series of linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector， ground power and control. Regardless of how you drive your servos， be it with an RC receiver， an Arduino board， or a VEX micro-controller， the PQ12-R servo will function in place of a regular servo， but with the added benefit of providing linear motion. The PQ12-R is available in a 20mm stroke coupled with gear ratio options of 30：1， 63：1 and 100：1 cover a large variety of applications.。The PQ12-100-6-R has：a 100：1 gear ratio for maximum lifting force； 6VDC operating voltage； and a servo(PWM)interface. This powerful little actuator can lift 50N(～5kg)!。The datasheet doesn't mention a minimum operating voltage， but we've tested this actuator at 5VDC and it seems to work just fine. The maximum force and movement speed are reduced of course.。Features。Gearing Option：100：1。Peak Power Point：40N @ 6mm/s。Peak Efficiency Point：20N @ 8mm/s。Max Speed(no load)：10mm/s。Max Force(lifted)：50N。Max Side Load：10N。Back Drive Force：35N。Stroke：20 mm。Input Voltage：6 VDC。Stall Current：550mA @ 6V。Mass：22g。Operating Temperature -10℃ to +50℃。Positional Repeatability：±0.1mm。Mechanical Backlash：0.25 mm。Audible Noise：55dB @ 45cm。Ingress Protection：IP-54。Maximum Duty Cycle：20%。PWM(Servo)signal：Fully retracted：2.0ms @ 50Hz。Fully extended：1.0ms @ 50Hz
