 UDB - USB Digital I/O Board  (Elexol USB I/O 24)   

24 Channels of Digital I/O on the USB Bus
The UDB board is a versatile platform for controlling external circuits and devices through the USB ports. The board provides 24 individually programmable digital I/O channels for digital I/O, and is capable of fast USB transfers. It comes complete with a host interface application program and a full Windows API (Application Program Interface) for programming in VB or VC++.
The module features 24 5V level signal lines individually programmable as input or output.   As the module connects to the USB port, multiple modules can be connected to a single PC by the use of a USB hub or hubs.   Each module features a serial number and the PC can identify each module uniquely allowing for multiple modules to be connected for a single application.   The outputs of the module are able to source or sink up to 30mA per I/O, up to a maximum 50mA per port, to allow for direct connection to a variety of devices

4Q - 2015
SMC is a very unique Stepper Motor Control module with accompanying PC application (SMC Control Panel). This set has been designed from ground-up to teach and experiment with unipolar stepper motors. A 12 V / 7.5 degree/step motor is supplied with the product. Step rate, direction, and drive mode can be controlled by the user. Single-stepping is also possible. A bank of LEDs show which motor windings are being energized. A UDM module is required for connection to the PC, since the SMC module itself does not have USB capability. SMC can be used in three ways:
  • Stand Alone Controller - No connection to the PC. All controls and configuration is done through switches on the SMC Module. Single-stepping or continuous run is possible.
  • Computer Controlled - Step, Direction and the Drive Mode signals are supplied by the PC application.
  • Direct-Drive - PC application drives the motor windings directly through the power FET transistors on the SMC Module. Using the SMC C/P, students figure out the drive sequence to obtain the desired drive mode, direction, and the step rate.
LDI is also designed to illustrate and teach how to interface the computer to a 16-character by 2-line LCD module with back light.The LDI Control Panel application lets the user control all bidirectional signals that are connected to the LCD module. The program has a test mode where control signals and the commands are sent to the LCD module to assure that it is in good health and functioning as expected. Beyond that, however, the students need to figure out how to do all that on their own. A unique "Learn" mode of the program lets the users save and send a sequence of signals and commands to the LCD module to avoid having to do a lot of re-typing. An on-board PWM driver is used to control the intensity of the backlight LEDs. Experimentation can be done in either 4-bit or 8-bit communication mode.
LDI Module requires the UDM Module to connect to the PC via the USB bus. It needs a DC power source @ 0.5 A, 8-12 V DC.
