SBX2 adds a lot to your system -- a fast parallel LCD interface, 4x5 keypad interface, 24 bits of fast, high-current open-drain bidirectional I/O, and RS232/485/IrDA serial I/O.

SBX2 uses a Xilinx CPLD to present just one CMOS load to the address and data bus (very important on TINI and other high speed micro systems). The CPLD buffers the LCD so that it can safely be located 12-24 inches away from the SBX board. The CPLD performs the LCD timing so that your controller doesn't have to slow down for the LCD.

The most popular LCD display is our 20x4, supertwist, LED backlit display. Customizable keypads are also available.

SBX2 uses a 2mm Serial Adapter for the RS232 or IrDA output connection. RS485 uses screw terminals (the green connector in the lower right corner of the photo).

SBX2 is discontinued. We recommend you use the Amulet Technologies LCD/touchscreen instead. Here is one example for JStamp along with a link to Amulet.

SBX2 LCD Connector: The LCD connector on the SBX2 board is Molex 22-23-2161. The matching cable receptacle is 22-26-8161, but almost any 0.1-inch spaced receptacle which accepts .025-square posts will work. You can use an IDC ribbon cable receptacle, 2 x 16 or larger and one row of pins will just be unused. We used to be able to get a cable and connector assembly for this, and sold it with the LCD, but that has not been available for some months now.
