Microprocessor Application Board

Microprocessor studying now a day is usually concentrated around programming with limited system expansion session, giving inadequate in-dept knowledge of microprocessor system integration for the purpose of device controlling to function systematically.  This often results in inability to apply the knowledge to real applications.

The unit is a self-contained microprocessor interface board with numerous system expansion components, enabling comprehensive hand-on experiments both Open & close-Loop controlling.  Modular structure of the unit allows free imagination on microprocessor system application.

Features:

- Interface to all types of microprocessor and microcontroller with a parallel port.

- Contains more than 20 experiment circuitries.

- Direct interface to external devices.

- Interfaces to a microcomputer.

- Contains a Stain Gauge Circuitry, applicable as a Weighting Scale.

- Modular design for ease of experimenting.

- Each circuit may be experimented individually, or may be connected in conjunction with other circuits to form a control - system.

- Experiment both Open & Closed-Loop controlling.

- Experiment module housed on a strong and durable steel encloser.

- Operations manual and Experiment sheets are inclusive.

- One-year warranty.
