SparkFun Capacitive Touch Slider - CAP1203 Qwiic
SPARKFUN¥2,498税込¥2,7481個33日以内出荷。Description。Do you want to replace a slider or a button on your art project or science experiment with a more interesting interface? This Capacitive Touch Slider is a "Qwiic" and easy way to add capacitive touch to your next project. With the board's built in touch pads, you can immediately start playing with the touch capabilities as three unique touch inputs or as a slider. You can also enable a touch input to act as a power button, customize the sensitivity for your own touch pads, and play with the interrupt alert LED. Utilizing our Qwiic system, no soldering is required to connect it to the rest of your system. However, we have broken out 0.1"-spaced pins in case you prefer to use a breadboard or create your own touch pads.。On the front of the board, there is an arrow shape which contains three separate capacitive touch pads. We also broke out the capacitive touch sensor lines as plated through-holes on the top of the board. You can use these pins to connect to your own capacitive touch pads. The CS1 pin connects to the left pad, the CS2 pin connects to the middle pad, and the CS3 pin connects to the right pad.。NOTE:The I2C address of the CAP1203 is 0x28 and is hardware defined. A multiplexer/Mux is required to communicate to multiple CAP1203 sensors on a single bus. If you need to use more than one CAP1203 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 SparkFun Capacitive Touch Slider Guide。Features。Capacitive Touch。3 unique capacitive touch inputs。Features。Emulated slider。Power button setting。Programmable sensitivity。Automatic recalibration。I2C Address:0x28。Qwiic Enabled。Operating Range。Supply Voltage:3.3V - 5Vアズワン品番67-0427-06
SparkFun Real Time Clock Module - RV-1805 Qwiic
SPARKFUN¥7,798税込¥8,5781個33日以内出荷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. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector.
