DescriptionThe TFMini Plus is a ToF(Time of Flight)LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters(+/- 5cm up to 6m)and as far as 12 meters(+/-1% starting at 6m)! As with all LiDAR sensors， your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object， but what makes this sensor special is its size. Measuring only 35x18.5x21mm， the TFMini Plus allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.Setting itself apart from the original TFmini， the TFmini Plus has been designed with an IP65 enclosure meaning its "Dust tight water resistant"， and also passed the vibration test of drone level， which will greatly expand its application range. The TFMini Plus is easy to power at only 5V and easy to talk to using the UART communication protocol.Important：This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR，" although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation ― as is performed by the Sharp GP-series devices.FeaturesOperating Range - 0.1m～12m1Accuracy - ±5cm@(0.1-6m)， ±1%@(6m-12m)Distance resolution - 5mmFrame rate - 1-1000Hz(adjustable)Ambient light immunity - 70kluxOperating temperature - -20℃～60℃Enclosure rating - IP65Light source - LEDCentral wavelength - 850nmFOV - 3.6°Supply voltage - 5V±0.5VAverage current - ≦110mAPower consumption - 550mWPeak current - 500mACommunication level - LVTTL(3.3V)Material of enclosure - ABS+PCStorage temperature - -20℃～75℃Weight - 11gWire length - 30cm

DescriptionIntroducing the SparkFun FT231X Breakout board， complete with the full UART hardware handshake feature! The pin-out of this board matches the FTDI cable to work with official Arduino and cloned Arduino boards. It can also be used for general serial applications.This board still brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto-reset any Arduino board that has the reset pin brought out to a 6-pin connector.The coolest thing about the FT231X Breakout is that we have broken out ALL the pins for your use， making this board all the more hackable! It also uses a common microUSB jack.One of the features of this board is a jumper on the back， which allows the VCC output to be configured to either 3.3V or 5V. This board ships default to 5V， but you can cut the default trace and add a solder jumper if you need to switch to 3.3V. It should be noted that the max input of the FT231X is only 3.3V， but it can operate down to 1.8V with external pull-ups and is also 5V tolerant.

DescriptionThe Mountable MI：pro is a simple and compact protective case for the micro：bit.

DescriptionSometimes referred to as "spade connectors，" these quick disconnects are really useful as power connectors in prototyping or in projects that are repeatedly assembled and disassembled. The shape of these connectors allows them to be used with a variety of retro game-cabinet buttons， as well as lights similar to the ones found in our Spectacle line.These Female Quick Disconnects are about 1/4" wide， come in packs of five， and can be affixed to a 16-14 AWG wire. Mating connectors can be found in the similar items section below.

DescriptionGet 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. 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 RV-1805 Real Time Clock Module GuideFeaturesOperating Voltage(Startup)：1.6V - 3.6VOperating Voltage(Timekeeping)：1.5V - 3.6VOperating Temperature：-40℃ - 85℃Time Accuracy：±2.0 ppmCurrent Consumption：22nA(Typ.)I2C Address：0xD2Supercapacitor for Backup Power2x Internal Oscillators2x Qwiic Connectors
