[Course Design] Ultra-small infrared boot card

It’s nearing the end of the semester and I can’t finish the document, so I’ll just make do with it.

Ultra-small infrared boot card based on esp8266

Introduction

A remote power-on card designed using the esp8266ex chip controls the computer's power on and off, and uses infrared decoding to connect to Tuya Smart to achieve linkage with other smart furniture.

At the same time, the occupation of the PCIE slot is taken into consideration. Currently, graphics cards generally occupy an additional second PCI-E x1 slot (blocked by the fan). This card can be perfectly inserted into the blocked slot.

Introduction to onboard resources

One LED, the wiring is consistent with the ESP12 module

An infrared receiver can only be connected to IO14 of ESP8266

2p 2.54 pin header, used to connect to the PANEL interface of the motherboard

Circuit functional analysis

Precautions:

PCIE board thickness is 1.6mm, be careful not to enter the wrong thickness

The code needs to be modified by 5 lines of configuration, with comments.

In order to compress the space as much as possible, the resistors and capacitors in the 0402 package are basically used, and it is difficult to weld.

At present, the #WAKE signal wake-up through PCIE has not been implemented, and no relevant information can be found.
