Serial Display Daughter Board for 16x2 display with a high speed

The LCD2S-162 is a RoHS compliant Serial LCD Daughter board that can be connected to a standard 16x2 Character Display Module that supports 4 bit mode. All 16x2 Character Modules sold on our site support 4 bit mode, and nearly all commercially available 16x2 line character modules support it too. We have not found a single 16x2 LCD display from any manufacturer that does not support 4 bit mode yet! The LCD2S-162 has a high speed SPI/I2C serial bus. For convenience the I2C and SPI signals are available via a Micro Match type connector, and a standard 2.54mm, 2x5 row pin header. Most new Modtronix SBC boards have Micro Match connectors, and can be connected to the LCD2S-162. The MICROMATCH-6MW Micro Match connector can be used to create a cable to connect the LCD2S-162 and SBC boards together. Or, our 150mm or 300mm Micro Match cables can be use.

A 2-way DIP switch is used to configure the unit for SPI or I2C operation (3 different addresses). The SPI mode is very simple, and enables the user to control the display via a very simple software routine. For more complex configurations, and multiple displays, the I2C bus can be used. The contrast and backlight are software controlled, and can be set to 254 levels.

A keypad with up to 16 buttons (4 rows by 4 columns) can be added to the display via a standard 10 pin, 2.54mm header. Our 12 button or 16 button keypads can be used, and can be connected to the LCD2S-162 via the CAB16RIB150 ribbon cable. When using the I2C serial bus, an interrupt line will be activated when a key is pressed, informing the user that there is key data to be read. Alternatively the LCD2S-162 can be polled to see if it has any pending keypad data.

The displays has 5 user configurable, general purpose inputs/outputs. Two of them can deliver up to 1000mA each, and have protection circuitry for driving relays.
