Portable electronic technology experimental box

Abstract

The invention provides a portable electronic technology experimental box. The portable electronic technology experimental box is small and exquisite in size, good in upgrading property, strong in compatibility and wide in usage. Besides, not only are needs of electronic technology fundamental experimental curricula met, but also the experimental box can be used as an experimental platform for student independent innovation practices, and the experimental box provides a good experimental environment for students to participate technological innovation and electronic design competitions. The portable electronic technology experimental box comprises a main board, two daughter boards, an experimental box body and a power supply module, wherein the main board comprises a nixie tube, a dial switch, an indicator light, a logic pen, a main switch, a direct voltage and a short circuit alarm, expansion wiring, an impulse signal source, a single impulse, a fixed resistor-capacitor, an alarm circuit, an A / D or D / A switch, a bread board and other modules. The two daughter boards are respectively a singlechip system board and a programmable system-on-chip board. The size of the singlechip system board is the same with the size of the bread board, thus the singlechip system board is convenient to dismantle and change. The introduction of the programmable system-on-chip board enables online programming to be realized, flexibility and convenience of the experimental box is strengthened, and the introduction of the two daughter boards enables the experimental box to upgrade to a high-performance singlechip system experimental box.
