{"product_id":"grove-12-channel-capacitive-touch-keypad-attiny1616","title":"Grove - 12-Channel Capacitive Touch Keypad (ATtiny1616)","description":"\u003cp\u003eThis 12-button keypad is built around the ATtiny1616, an 8-bit AVR processor that runs at up to 16 MHz. It has an integrated QTouch peripheral touch controller that supports capacitive touch interfaces with proximity sensing and a driven shield. With this module, creating an Arduino password keypad or a DIY phone keypad becomes easy.\u003c\/p\u003e\n\u003cp\u003eThe keypad has a 3 x 4 layout, similar to a mobile phone keyboard. Traditional keypads require 3 vertical and 4 horizontal lines to scan, occupying 7 I\/O pins on the microcontroller. With the ATtiny1616 and the Grove connector, only two pins (RX and TX) are needed for the keypad. You can easily use this module with any microcontroller such as \u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/thepihut.com\/collections\/arduino-store\"\u003eArduino\u003c\/a\u003e\u003cspan\u003e (With a \u003c\/span\u003e\u003ca href=\"\/zh\/products\/grove-base-shield-v2-0-for-arduino\"\u003eGrove - Base Shield\u003c\/a\u003e\u003cspan\u003e)\u003c\/span\u003e\u003cspan\u003e or \u003c\/span\u003e\u003ca href=\"https:\/\/thepihut.com\/collections\/raspberry-pi-store\"\u003eRaspberry Pi\u003c\/a\u003e\u003cspan\u003e (Only with the \u003c\/span\u003e\u003ca href=\"\/zh\/products\/grove-base-hat-for-raspberry-pi\"\u003eGrove-Base HAT\u003c\/a\u003e\u003cspan\u003e)\u003c\/span\u003e, or any that has a hardware UART connector or uses software UART to read button inputs with just two regular I\/O pins.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLow Power ATtiny1616 Controller\u003c\/li\u003e\n\u003cli\u003e3.3V \/ 5V Compatible\u003c\/li\u003e\n\u003cli\u003eCapacitive Touch, High Sensitivity\u003c\/li\u003e\n\u003cli\u003e12-button Keypad\u003c\/li\u003e\n\u003cli\u003e4-pin Grove UART Connector\u003c\/li\u003e\n\u003cli\u003eOn-board LED Indicator\u003c\/li\u003e\n\u003cli\u003eProduct Number: Seeed \u003cspan\u003e101020636\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"442\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"252\"\u003eSupply voltage\u003c\/td\u003e\n\u003ctd width=\"190\"\u003e3.3V \/ 5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCPU\u003c\/td\u003e\n\u003ctd\u003eAVR® 8-bit CPU @ 16MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor type\u003c\/td\u003e\n\u003ctd\u003eCapacitive Touch Keypad\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eButton Quantity\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperate temperature Range\u003c\/td\u003e\n\u003ctd\u003e-40°C to 105°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Interface\u003c\/td\u003e\n\u003ctd\u003eUART\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirmware Download Interface\u003c\/td\u003e\n\u003ctd\u003eUPDI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.seeedstudio.com\/Grove-12-Channel-Capacitive-Touch-Keypad-ATtiny1616-\/\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/files.seeedstudio.com\/wiki\/Grove-12-Channel-Capacitive-Touch-Keypad-ATtiny1616\/res\/Grove%20-%2012-Channel%20Capacitive%20Touch%20Keypad%20(ATtiny1616).zip\" rel=\"noopener\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/files.seeedstudio.com\/wiki\/Grove-12-Channel-Capacitive-Touch-Keypad-ATtiny1616\/res\/ATtiny1616-1617_Datasheet.pdf\" rel=\"noopener\" target=\"_blank\"\u003eATtiny1616 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePinout\u003c\/h3\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/Grove_12_Channel_Capacitive_Touch_Keypad_features_1.jpg?v=1728305325\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x \u003cspan\u003eGrove - 12-Channel Capacitive Touch Keypad\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed","offers":[{"title":"Default Title","offer_id":50847203393809,"sku":"106121","price":5.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/grove-12-channel-capacitive-touch-keypad-attiny1616-seeed-106121-43309204930755.jpg?v=1735208393","url":"https:\/\/abcd3032.myshopify.com\/zh\/products\/grove-12-channel-capacitive-touch-keypad-attiny1616","provider":"Tayyab Zak","version":"1.0","type":"link"}
