Kind tips:

1. The BOOT pin of esp8266 is GPIO0, which corresponds to the button of the socket

2. All programming-related pins have been reserved in the chip board. You can solder the leads as needed.

3. After downloading the program, when using the serial port to view the log, you need to use a 220v power supply (please be sure to observe power safety).

Reason: Since the socket contains power-consuming equipment such as relays and meters, the 3.3V voltage and current provided by the USB-to-serial port may be insufficient, which manifests as an intermittent connection between the USB-to-serial port and the computer, resulting in the inability to view the log.

Note: In order to reduce welding wires, the chip is reset by powering off and on the chip. You can also solder the EN pin lead and pull EN low and high to reset the chip.

Compile and download

  1. Open code project

  2. First click the Compile button to compile the project.

  3. Then click the Download button and wait for the device to enter download mode to download.

    At this step, for the new version of the esp8266 socket (4-pin base plate), you need to enter the download mode first, and then click the Download button

Put the device into download mode

How to enter download mode
1. First power off the 8266 module (disconnect the 3.3V connection between the USB to serial port module and the 8266)
2. Pull the IO0 of the 8266 module low (that is, press and hold the ssa, sse socket button)
3. Then power on the 8266 module (connect the 3.3V wiring between the USB to serial port module and the 8266)
4. When downloading, IO0 should always be pulled low (i.e., press and hold the ssa, sse socket button)
 (Tip: For the old version of esp8266 socket (3-pin base plate), in this step, IO0 can be pulled high and the button released;
        esp8266 new version socket (4-pin base plate), in this step, IO0 also needs to be pulled down all the time, i.e. hold down the button, otherwise the programming will be disconnected
  )
5. Wait until the download is complete.

Note that IO0 of 8266 is the key for ssa and sse socket products.
