{"product_id":"power-rtc-hat-for-raspberry-pi","title":"Power + RTC HAT for Raspberry Pi","description":"\u003cp\u003eTwo of the biggest challenges with the Raspberry Pi in portable\/mobile\/automotive applications is the lack of an accurate way to keep time and a flexible input DC power supply. This Power + RTC HAT for the Raspberry Pi solves this problem!\u003c\/p\u003e\n\u003cp\u003eOnboard is a fused and reverse polarity protected DC input coupled to a beefy 3A 5V DC\/DC converter. Connected to a 12V automotive battery, this board is happy running the Pi under heavy load all day long.\u003c\/p\u003e\n\u003cp\u003eSince a battery-powered Pi is not likely going to have reliable access to the internet to keep the time, we have also added a temperature compensated, DS3231 chipset by Maxim. The chip is connected directly to the I2C bus and uses address 0x68. Simply add a CR1220 battery (not included) to the holder onboard, set the time, and it will keep it within ±0.432 Second\/Day (roughly ±2 minutes a year) in temperatures ranging between -45°C and +85°C.\u003c\/p\u003e\n\u003cp\u003eTo make this board even more useful, we have also included two SparkFun Qwiic \/ Adafruit STEMMA QT connectors – this is an easy-connect system for I2C sensors, actuators, shields using pre-built cables that make prototyping faster and less prone to error. Add sensors and further expand your Pi’s monitoring and control capabilities as you need, with no soldering required.\u003c\/p\u003e\n\u003cp\u003eThis version is fully assembled – no soldering required. Just hook it up and you are good to go! The board is compatible with all “A” and “B” versions of the Raspberry Pi (Pi A+, B+, 2, 3, 3A+, 3B+, and Pi 4).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: Raspberry Pi and CR1220 battery not included.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"featurebox\"\u003e\n\u003cul\u003e\n\u003cli\u003eRTC Accuracy of ±0.432 Second\/Day\u003c\/li\u003e\n\u003cli\u003eTwo STEMMA QT \/ Qwiic connectors\u003c\/li\u003e\n\u003cli\u003eTwo Time-of-Day Alarms\u003c\/li\u003e\n\u003cli\u003eRTC Battery Backup: CR1220\u003c\/li\u003e\n\u003cli\u003e5V 3A Output to power Raspberry Pi\u003c\/li\u003e\n\u003cli\u003eDimensions: 65 x 56mm\u003c\/li\u003e\n\u003cli\u003eLeap-Year Compensation Up to Year 2100\u003c\/li\u003e\n\u003cli\u003eSeparate onboard 3.3V Regulator for Qwiic \/ STEMMA QT Bus\u003c\/li\u003e\n\u003cli\u003eComplete Clock Calendar Functionality\u003c\/li\u003e\n\u003cli\u003eMaximum Regulator Input: 36VDC\u003c\/li\u003e\n\u003cli\u003eRecommended Input: 7 – 16VDC\u003c\/li\u003e\n\u003cli\u003eHeight: 12mm\u003c\/li\u003e\n\u003cli\u003eWeight: 35g\u003c\/li\u003e\n\u003cli\u003eManufactured in Canada\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAdding an RTC to the Raspberry Pi\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BCRobotics","offers":[{"title":"Default Title","offer_id":48624151724250,"sku":"obp1789684807164","price":24.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/power-rtc-hat-for-raspberry-pi_1.jpg?v=1789684841","url":"https:\/\/memoryfoamwear.shop\/products\/power-rtc-hat-for-raspberry-pi","provider":"My Store","version":"1.0","type":"link"}
