For PS2 Keyboard Driver Module Serial Port Transmission Module Arduino AVR PS2 Keyboard Driver Module

Converts the PS2 protocol to TWI/IIC,UART,parallel interface Increase the key state detection. Wide range of applications. Application : Robot ,Electronic products,and so on Brief introduction: PS2 keyboard driver module, use a small microcontroller reads the PC PS2 keyboard key-press information, The values of the key will output by serial or parallel, for the use of other equipment. In a single chip microcomputer project system, main control MCU does not need to write the keyboard driver, read the key information directly, very convenient. PS2 keyboard driver module, use a small microcontroller reads the PC PS2 keyboard key-press information, The values of the key will output by serial or parallel or TWI/IIC (Through the short circuit cap option), for the use of other equipment. Matters need attention: 1.TWI/IIC address is 4. Modules for the host. 2.Do not use the TWI/IIC should be "IIC/TWI enable" Short circuit cap to remove. Otherwi se the module will not be able to work properly 3. *UART Baud rate: 19200 Performance parameter: 1>. working voltage:DC5V; 2>. Key information is sent out by serial(Baud rate 19200) and parallel 3>. corresponding speed; 4>. apply to PC PS2 keyboard. Color: Blue Material: PCB Package Contents: 1*Keyboard module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
