Note:please read the instructions carefully to drive plate no electric! In order to avoid incorrect connection driver board permanent damage. Please check the pin function instructions carefully pay attention to the concise identifier correct connection! Don't pick up the power cord to the resulting in electronics burned. Use Nokia 5110 LCD screen as display devices. SPI interface maximum limit save the I/O resources. Specially added five rocker convenient implementation structures human-computer interaction interface all the rest of the analog and digital interface with pin derivation easy to install sensors and other modules. This product is suitable for various development board and controller for example: the Arduino controller on STC microcontroller AVR microcontroller etc. Specifications: Product name: 1.65 "LCD4884 LCD rocker extension board. Modle: RB-05L007. Working voltage: DC 5V. Product type: the Arduino expansion board. Production process: FR4 double-sided tin. Humanization design: has the man-machine interactive interface "five rocker". Working temperature: 10 ? to 30 ?. On-board resources: DIGITAL: eight ANALOG IN: five 48 x 84 LCD: one Five rocker button: one system reset button: one.Application method: first plug module directly to the Arduino controller then use the USB cable connect the controller to the computer. LCD4884 Joystick shields extension plate test we use the Arduino controller to do a test should use hardware equipment as follows: Arduino controller x 1 LCD4884 Joystick Shield ×1 USB data line x 1. First plug module directly to the Arduino controller then use the USB cable connect the controller to the computer. This module requires the Arduino version 1.0 or above.
