You could upgrade to a board with massive number of GPIO like the Grand Central, or you could pop on one of these boards. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them. It's going to be slower than direct GPIO access, but maybe that doesn't matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I/O control!.／GPIO擴充器的工作原理是這樣的：你有一個帶有一定數量的GPIO的電路板，但不足以滿足你的專案 - 也許你需要更多的按鈕或LED。您可以升級到具有大量GPIO的板，例如 Grand Central，或者您可以在其中一個板上彈出。通過 I2C 連接它，然後您可以發送/接收 I2C 命令來控制 GPIO 引腳以寫入和讀取它們。它將比直接GPIO訪問慢，但如果它需要一毫秒而不是一微秒，也許這並不重要。您只需要兩個I2C引腳，您甚至可以與其他感測器和設備共用I2C埠。哎呀，您甚至可以添加更多擴展器來實現大規模的I / O控制！。 【The AW9523 is a twist on the common I2C expander】： - First up, its very affordable - who doesn't love that? - It has 16 I/O pins, that'll double most boards' pin count - Four I2C address options, so you can connect 4 expanders to one bus - Each pin can be an input or an output - IRQ output can alert you when input pins change value - This chip does not support internal pull-ups or pull-downs, you will need to add an external resistor if you... ## 圖片 | 類型 | 圖片 URL | 說明 | |---|---|---| | 主圖 | https://img.yec.tw/ob/image/cf59dd0c-2bb2-4b16-be14-8373f8d66224.jpg | 商品主圖 | | 細節圖 | https://img.yec.tw/ob/image/1aacdfae-3af5-4975-83fa-5fb45e93e26a.jpg | 商品圖片 2 | | 細節圖 | https://img.yec.tw/ob/image/e310649e-1d38-49a0-bde4-00628fc039d9.jpg | 商品圖片 3 | | 細節圖 | https://img.yec.tw/ob/image/4fabb700-a603-4a60-ae07-e1a88bd7d550.jpg | 商品圖片 4 | ## 運送與付款 運送方式： | 方式 | 費用 | |---|---:| | 郵局掛號 | 免運費 | | 7-ELEVEN取貨付款 | 免運費 | | 7-ELEVEN取貨不付款 | 免運費 | 付款方式： - ATM轉帳 - 7-ELEVEN取貨付款 ## 退換貨政策 依照消費者保護法規定，網購商品享有七天猶豫期（非試用期），特殊商品除外。 ## Canonical URL https://tw.bid.yahoo.com/item/100494723402
