6-port serial communication interface board

Abstract

The invention provides a 6-port serial port communication interface board, comprising a circuit board, and six communication interfaces and a power socket which are arranged on the circuit board, wherein the circuit board is rectangular; the six communication interfaces comprise a first subordinate machine communication interface and a second subordinate machine communication interface which are arranged on a first rectangular edge of the circuit board in parallel, a third subordinate machine communication interface which is arranged at a second rectangular edge of the circuit board, a fourth subordinate machine communication interface and a fifth subordinate machine communication interface which are arranged at a third rectangular edge of the circuit board in parallel, and a host machine communication interface; and the host machine communication interface and the power socket are arranged at a fourth rectangular edge of the circuit board in parallel; all the subordinate machine communication interfaces are connected with one another in parallel and the host machine communication interface is crossly connected with each subordinate machine communication interface.

Description

【Technical field】 [0001] The invention relates to the field of electronics, in particular to a 6-port serial communication interface board. 【Background technique】 [0002] Existing electronic toys are various, and these electronic toys usually include a whole circuit board, and various electronic components are arranged on the circuit board to realize certain electronic functions. For example, more and more electronic toys on the market now have the function of sound playback, and can play various pleasant music. In order to improve the volume and effect of music playing in this electronic toy with music playing function, a power amplifier unit for amplifying the sound is usually arranged on the circuit board. [0003] However, the electronic part of the current electronic toy is a whole circuit board. When a certain component on the circuit board breaks down, the entire circuit board cannot work, and the entire electronic toy cannot realize the original electronic function...

AI Technical Summary

Problems solved by technology

[0003] However, the electronic part of the current electronic toy is a whole circuit board. When a certain component on the circuit board breaks down, the entire circuit board cannot work, and the entire electronic toy cannot realize the original electronic function. Ordinary users can only discard toys, causing waste

[0004] On the other hand, the existing electronic toys are toys with fixed shapes and structures, and users will not have more interest after playing for a period of time.

Now more and more players like to make various electronic toys by themselves, or modify the original electronic toys. Most of the existing toys are not disassembled. Even if they are disassembled, the product may not be restored. And it cannot be assembled into other toys after disassembly
