(SKU:RB-05L007)LCD4884液晶搖桿擴(kuò)展板

產(chǎn)品概述

最新推出的LCD4884 LCD Joystick Shield v2.0 LCD4884液晶屏擴(kuò)展板是哈爾濱奧松機(jī)器人科技有限公司研發(fā)的一款黑白屏液晶擴(kuò)展板。此擴(kuò)展板采用Nokia 5110液晶屏為顯示器件。SPI接口，最大限度的節(jié)省I/O資源。特別添加五向搖桿，方便實(shí)現(xiàn)搭建人機(jī)互動接口，剩余的模擬與數(shù)字接口全部用插針引出，便于安裝其它傳感器與模塊。本品適用于各種開發(fā)板和控制器，例如：Arduino控制器、STC單片機(jī)、AVR單片機(jī)等。
