Electronic motherboard, electronic equipment and debugging system

Abstract

The invention discloses an electronic main board, electronic equipment and a debugging system, wherein, the electronic main board uses a disposable battery for power supply, and the electronic main board includes: a micro control unit, including a power input terminal and a signal pin, a power input terminal and a disposable battery Connection; the port is connected to the signal pin of the microcontroller unit, and the port is used to connect peripheral devices; wherein, the port includes a power supply pin, and the power supply pin is connected to the disposable battery through the first unidirectional conductive device, and the first unidirectional electrical conductor The positive pole of the component is connected to the disposable battery, and the negative pole of the first unidirectional conductive component is connected to the power supply pin. By setting the first unidirectional conductive device between the power supply pin of the port and the disposable battery, the peripheral device is prevented from charging the disposable battery through the port after the port is connected to the peripheral device, thereby preventing the charging of the disposable battery due to Charging, resulting in the risk of burning the electronic motherboard or debugging tools or exploding disposable batteries.

Description

technical field [0001] The invention relates to the technical field of development and debugging, in particular to an electronic main board, electronic equipment and a debugging system. Background technique [0002] With the advancement of urban refined management and the development of Internet of Things technology, reducing the secondary costs incurred in the operation, maintenance and repair of electronic equipment and systems has become more and more recognized by enterprises and institutions, and the design of maintenance-free and highly reliable electronic Products and systems are requirements for manufacturers as well as designers. Among them, disposable batteries are also widely used for IoT products with low power consumption, long battery life, and maintenance-free. [0003] Lithium-sub-battery is an example of a disposable battery, which has the advantages of large capacity, small size, low cost, and high reliability. However, it cannot be charged during the appl...

AI Technical Summary

Problems solved by technology

[0004] For some electronic devices that use disposable batteries, before they are put into use, development engineers will use debugging tools to power the electronic motherboards of electronic devices during the embedded development process, and some engineers directly use disposable lithium-sub-batteries to power electronic motherboards. If there is no special treatment for the electronic motherboard, once the development engineer makes a mistake and uses a debugging tool to power the electronic motherboard, and also uses a disposable battery to power the electronic motherboard, the electronic motherboard or debugging tool will be burned at the slightest, and the disposable battery will be damaged due to being charged. accidental explosion
