DescriptionKeypads are very handy input devices， but who wants to tie up seven GPIO pins， wire up handful of pull-up resistors， and write firmware that wastes valuable processing time scanning the keys for inputs? The SparkFun Qwiic Keypad comes fully assembled and makes the development process for adding 12 button keypad easy. No voltage translation or figuring out which I2C pin is SDA or SCL， just plug and go! 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 breadboard.Each of the keypad's 12 buttons has been labeled 1， 2， 3， 4， 5， 6， 7， 8， 9， 0， *， and and has been formatted to into the same layout as telephone keypad with each keypress resistance ranging between 10 and 150 Ohms. The Qwiic Keypad reads and stores the last 15 button presses in First-In， First-Out(FIFO)stack， so you don't need to constantly poll the keypad from your microcontroller. This information， then， is accessible through the Qwiic interface. The SparkFun Qwiic Keypad even has software configurable I2C address so you can have multiple I2C devices on the same bus.NOTE：The I2C address of the Qwiic Keypad is 0x4B and is jumper selectable to 0x4A(software-configurable to any address). multiplexer/Mux is required to communicate to multiple Qwiic Keypad sensors on single bus. If you need to use more than one Qwiic Keypad 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 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 Keypad Hookup GuideFeaturesSoftware Selectable Slave AddressLow Power ATtiny85 controllerButton Presses w/ Time StampDefault I2C Address：0x4B2x Qwiic Connector

RS PRO Cable Tie Mounts， Saddle MountIntroducing the range of RS PRO Cable Tie Mounts， designed to provide maximum stability for wire bundles. They can be used both indoors and outdoors thanks to the durable Nylon 66 material， making them ideal for harsh conditions with high and low-temperature extremes. Saddle type cable tie mounts are easy to install by simply fixing them with a screw and securing the wire bundles with the cable tie. These types of mounts are incredibly versatile and can be used as a secure base from cable management purposes to securing climbing plants， and so much more.Features and Benefits:The RS PRO non-adhesive cable tie mount range offers an easy to use cable tie mounting base with quick installation and ultra-secure fixing， even by hand The high tensile strength of the nylon material provides a strong fastening base for the cable tie to strap on to even when under high tension Made from high-quality PA66MP (Nylon 66) that offers high strength and wear resistance， even at high and low-temperature extremes Nylon cable tie mounts have excellent chemical resistance for food and pharmaceutical processing， equipment and manufacturing applications In addition to this， these cable tie mounts have been designed to have a greater resistance to UV exposure， making them ideal for outdoor applications Available in a range of neutral colours for discreet cable management or tidying Supplied in a pack of 100Applications:RS Pro サドルタイプタイマウントは、 UL 認定ナイロン 66 、 94V-2 素材を使用します。ナチュラルカラーですが、他の色のものもあります。サドル設計により、ワイヤバンドルの安定性が最大限に高められます。取り付けるには、ねじで取り付け、ナイロン製ケーブルタイでワイヤ束を固定します。Are these mounts re-usable.耐紫外線性はありません 最低動作温度： -40 ° C 最大動作温度： 85 ° CNo， these mounts are single-use only， so it is important to ensure regular checks are undertaken to ensure they have not perished over time， especially when they are being used in environments with exposure to rapid and extreme temperature changes or chemicals.Why RS PRO.RS PRO is our own brand range and brings you a wide range of high-quality， great value products offering you more choice. Trusted by engineers all over the world， every part of every RS PRO product has been rigorously tested against demanding industry standards； they’re only given the RS PRO seal of approval if we’re confident of their exceptional quality， which means you can be confident too.Standards and Certifications:UL 94 V-2 RoHS Compliant Halogen Free
