Socket model of punctual atom stm32f429 core board

Abstract ： The punctual atoms STM32F429 Core board is widely used , It can be inserted into the functional backplane for design and development . So developers can focus on the implementation of core functions , There is no need to care about the stability of the high-speed circuit . What is the external interface model of the core board ？ What is the pin distribution of the core board ？ This article introduces .

1. Core board external interface model

The core board adopts B2B（ Board to board ） The connector . Compared with the needle arrangement , Easier disassembly and assembly , There are no problems such as bending pins .

The back interface is shown in the figure below .

  What are the models of these two sockets ？

The two sockets installed on the core board , yes 3710F Socket （ Male head ）.

So the corresponding is 3710F Socket （ Female seat ）, As shown in the figure below . It has 60 One pin , On both sides 30 individual .

 

  The official website of punctual atom has this purchase connection , You can search “3710F Board to board connectors ” Find purchase .

2. Core board external interface pin distribution

As shown in the figure below , This is the pin distribution of the two sockets .

  So how to distinguish which socket is which ？ We just need to identify three VCC The pin can be determined . As shown in the figure below

The three pins in the red box are VCC5, There are only three on one socket VCC5 Pin . Other pins , According to the schematic diagram, you can compare and distinguish one by one .
