The ARM9 is an electronics development board with the add-on ARM9 board. ARM is the industry’s leading provider of 32-bit embedded RISC microprocessors, offering a wide range of processors based on a common architecture and delivering high performance together with low power consumption and system cost.

The ARM9 provides a learning platform for this important RISC Microprocessor. With an easy to use operational systems and development process, simply enter commands directly into the CPU.

The basic electricity trainer can be used to develop the student’s abilities and teach basic electrical circuits such as series and parallel circuits, electromagnet induction, coil behaviour with AC and DC circuits, diode and transistor characteristics etc. This simple training kit provides a strong operation for future studies in electrical or electronics.

The PCI application is now widely used and has replaced the ISA system. PC-based interfacing and I/O experimentation had been based on the ISA (Industry Standard Architecture) bus, however, the PCI (Peripheral Component Interconnect) bus, makes it much more difficult for users to interface their own circuits directly to the PC. The PCIDT rectifies this situation enabling the experiments to be carried out via the PCI bus.

The PCIDT provides a solution for teaching PC-based interfacing to various I/O devices on modern PCs using the PCI bus. Pre-written experiments cover I/O devices from switches and 7-segment displays and A/D and D/A conversion to the optional DC and stepper motors. A complete introduction to PC interfacing covering PC interfaces and how to connect a range of common I/O devices is provides along with twelve experiments, with their program listings in assembly language and C, based on the PCIDT’s pre-wired circuits. Using the exercises in the textbooks and tools, users are able to learn quickly in controlling I/O under Windows through a PCI interface card. Users can develop and learn PCI I/O control, in addition experiments with C or VB language. The system contains two main units: the interface card and the experiment platform. The design ensures that none of the experiments require soldering. The unit is enclosed in a strong and durable case.

The Power Electronics Lab is used to perform power electronics circuit experiments.
