Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] This embodiment provides a portable electronic technology experiment box, which is small in size, easy to move and carry, has complete functions, and adopts a modular design with good compatibility and expandability.
[0027] The experiment box includes a box body 1, a power module 4, a main board 2 and two sub-boards. The two daughter boards in this embodiment are MSP430 daughter board and PSoC5 daughter board respectively.
[0028] Wherein the box body 1 is a square structure, such as figure 1 As shown, its size is 230mm in length, 230mm in width and 100mm in height. The main board 2 is fixed inside the box body 1, and the power module 4 is fixed on the inner surface of the bottom of the box body 1. The power module 4 is used to convert the mains power into ±5V, ±12V DC voltage to supply power for the main board 2 and two sub-boards. The w...

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.
Description
technical field [0001] The invention relates to a portable electronic technology experiment box, which belongs to the field of electronic technology.
