WLKBI2CS Wired/Wireless USB to I²C, SPI & RS232 Keyboard Adapter Home

Converts a wired or wireless USB keyboard to a programmable I²C/SPI/RS232 keyboard for non-USB systems!

Works with any standard USB keyboard

4-30VDC operating power

Screw terminals and 10-pin flat cable connections

Programs via COM port (with Windows app)

See the RS232-Only models

Uses any standard wired or wireless USB keyboard converting it to I²C/SPI/RS232 for general use as an I²C or SPI slave, or RS232 device. WLKBI2CS is the first device to provide a simple USB HID Composite host which can communicate with a standard USB keyboard and convert the keycodes to standard ASCII characters. In addition the WLKBI2CS can be user-programmed to override the standard key-cap characters and output alternate characters or strings (up to 10-characters) for any keypress. User configurable selection of I2C or SPI -- RS232 port is always active.

Compatible with 1.8V-5V I²C and 3V-5V SPI signals

APPLICATIONS

Systems without USB support, or no HID drivers
Replacement for RS232 CNC keyboards at reduced cost
Systems needing keyboard with no available serial port
Embedded systems needing wireless keyboards

DESCRIPTION

WLKBI2CS is a 2.8" X 1.7" X 0.8" module which provides translation of USB keycodes to ASCII characters. This allows even small microcontroller systems to incorporate USB keyboards without any of the development complexity of USB and HID drivers. ASCII key-cap characters are available from the keyboard by connecting the WLKBI2CS to your system via I²C, SPI or RS232 using the screw terminals or flat cable connector. By operating with standard industry-leading wireless keyboards you get the assurance of a reliable RF link. Manual available here

Typically works with all USB keyboards or keyboard/mouse dongles which do NOT require special drivers to operate on a PC. Although some keyboards include a driver CD for special features, many work with the default Microsoft OS USB drivers and these will work with the WLKBI2CS. Versalent can help determine if your keyboard is compatible.
