Remote boot card_ESP01S

The ESP01S module has four IOs, but only RX (IO3) does not produce a level jump when powered on. It defaults to pull-up when powered on, and defaults to low level after startup. Although it is not perfect, it at least works. It’s hard to describe other IOs. They will all jitter when powered on. They can be used as inputs, but pull-up inputs must be used, otherwise the module cannot enter the running state.
 
IO allocation and functions:
IO0: BOOT button, used for program burning and long pressing for 5 seconds will reset the distribution network information;
IO1: Power-on detection input pin;
IO2: Onboard LED light displays network status, network distribution and unsuccessful networking flashes, and stays on after successfully connecting to the network and connecting to the blinker server;
IO3: controls the computer to turn on and off.
 
Physical picture of PCB:
 
 
This boot card requires an extension cable. The Power Switch terminal (XH2.54) has 4 pins. The upper and lower 2 pins are divided into two groups. One group is connected to the power sw of the motherboard (using 2P female header), and the other group is connected to The power SW of the chassis (uses 2p pin), the two sets of wires are not divided into positive and negative polarities. The length is cut according to your own chassis, as shown in the picture below.
 
 
This code is not open source, but the bin file and blinker interface configuration file will be uploaded. The following describes how to use it. First, learn how to create a device with blinker and import the blinker interface configuration I uploaded. Secondly, burn the code and restart, the onboard LED will enter the blinking state, and the NetWaker-WIFI network will be released after 10 seconds. After connecting to this wifi, the WEB configuration page will pop up, enter the wifi information and the key of the blinker device. Then click Save. If the entered information is correct, the onboard LED will flash and then turn on, and the Blinker device will also show that it is online. Finally, shut down the computer and cut off the power, insert the boot card into the PCIE slot, and connect the extension cable to the motherboard boot port and chassis boot cable respectively. Power on the computer and observe the status of the onboard LED. If it does not light up, go to the BIOS to adjust the pcie option of the power supply APM. If it flashes briefly and then stays on, then it is basically ok. Use blinker for a boot test.
