LCD Modules with built in I2C, RS232 or USB connection. These LCDs are designed to be the quickest way possible to get your design up and running. The RS232 connector is wired so that a standard "straight through" 9 pin D-sub cable may be used to connect the modules on a standard serial port such as comm ports on PCs. In addition, We have been successful in developing some USB module ( Such as 16*2, 20*4, 40*4, 128*64, 192*64, 320*240 etc ). For more information, contact S-Tek Displays at 440-439-8232.
