The LK204-7T-1U is an intelligent alphanumeric liquid crystal display designed to decrease development
time by providing an instant solution to any project. In addition to the RS232, TTL and I2C protocols
available in the standard model, the USB communication model allow the LK204-7T-1U to be connected
to a wide variety of host controllers. Communication speeds of up to 115.2kbps for serial protocols and
100kbps for I
2 C ensure lightning fast text and graphic display.
The simple command structure permits easy software control of many settings including backlight
brightness, screen contrast, and baud rate. On board memory provides up to forty custom characters
