We have two STEMMA QT connectors on either side for quick connectivity. The physical size of the board and two mounting holes location have not changed. However, we did change the power/I2C breakout section pinout to match our standard pinout order!\n\n    自2021年1月21日起-我們已將該傳感器更新為STEMMA QT傳感器標準。兩側都有兩個STEMMA QT連接器，用於快速連接。電路板的物理尺寸和兩個安裝孔的位置均未更改。但是，我們確實更改了電源/ I2C中斷部分的引腳排列，以匹配我們的標準引腳排列順序！\n\n　　Add lots of touch sensors to your next microcontroller project with this easy-to-use 12-channel capacitive touch sensor breakout board, starring the MPR121. This chip can handle up to 12 individual touchpads.\n      這款易於使用的12通道電容式觸摸傳感器分線板由MPR121為主，可以在您的下一個微控制器項目中添加很多觸摸傳感器。該芯片最多可以處理12個單獨的觸摸板。\n　　　　The MPR121 has support for only I2C, which can be implemented with nearly any microcontroller. You can select one of 4 addresses with the ADDR pin, for a total of 48 capacitive touch pads on one I2C 2-wire bus. Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you and can be configured for more/less sensitivity.\n       MPR121僅支持I2C，幾乎可以用任何微控制器來實現。您可以使用ADDR引腳選擇4個地址之一，以便在一條I2C 2線總線上總共使用48個電容式觸摸板。使用該芯片比通過模擬輸入進行電容感測要容易得多：它可以為您處理所有濾波，並且可以配置為更高/更低的靈敏度。\n　　　　This sensor comes as a tiny hard-to-solder chip so we put it onto a breakout board for you. Since it's a 3V-only chip, we added a 3V regulator and I2C level shifting so it's safe to use...","shipping_methods":[{"name":"郵局掛號","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨不付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","7-ELEVEN取貨付款"],"category_id":"2092072544","category_name":"其他電腦周邊","breadcrumb":[{"id":"23336","name":"電腦、平板與周邊","url":"/tw/%E9%9B%BB%E8%85%A6%E3%80%81%E5%B9%B3%E6%9D%BF%E8%88%87%E5%91%A8%E9%82%8A-23336-category.html"},{"id":"2092072522","name":"電腦/筆電周邊","url":"/tw/%E9%9B%BB%E8%85%A6-%E7%AD%86%E9%9B%BB%E5%91%A8%E9%82%8A-2092072522-category.html"},{"id":"2092072544","name":"其他電腦周邊","url":"/tw/%E5%85%B6%E4%BB%96%E9%9B%BB%E8%85%A6%E5%91%A8%E9%82%8A-2092072544-category.html"}],"view_count":0,"watch_count":0}
