The LCD2S-204 is a RoHS conform interface board, which arrange a standard 20x4 characters alphanumerical LCD module with a high speed SPI and I2C bus. The small module can be soldered with a 16-pin strip on the backside of the board directly to a LCD module (with a HD44780 or compatible LCD controller). Thus you can connect a alphanumerical LCD module pin saving to a SPI or I2C bus of a microcontroller or another system. The I2C and SPI bus signals are available at the AMP MicroMatch female connector and additional at a 2.54mm strip (2x5-pin).

The following Single Board Computer (SBC) from our product range features also about a MicroMatch connector and can connected directly to the LCD2S inferface board: SBC28DC, SBC28PC-IR2, SBC28PC-IR4, SBC44B, BLC877A, SBC66EC, SBC65EC and SBC68EC.

A small DIP switch enables the choice of communication mode (SPI or I2C) as well as the placing of 3 different I2C adresses and permitted the operation up to three LCD2S interface boards. The SPI mode is a very simple bus system for a synchron serial data transfer about a bidirectional three-wire interface with very simple software routines. For complex configurations (e.g. more than one display at the bus) the I2C bus can be used.

The contrast and the background lighting are controlled about software and can be changed in 254 levels. A keyboard with until 16 push buttons (4 rows and 4 columns) can connected optional to the LCD2S module with a 10-pin strip (grid 2.54 mm). In the I2C mode a separate interrupt signal wire informs about a keyboard event. The pushed button can called about a read instruction. Altenative you can use the LCD2S module in polling operation for a pressed button.

The LCD2S module features 5 user programable input or output wires. Two of the I/O-pins can operate up to currents of 1000mA and provides a protection circuit for the connection of relays.
