Recently, I am particularly interested in the esp8266 network clock. I saw that many big guys are using esp12f as the main control. Since these stamp holes are a bit difficult for a novice like me to solder, and many pins are not used, so I simply use esp01 As the main control, I drew a board to drive the 1.3-inch OLED, and then tested it and it still works. It is very simple and easy to use. The pin sequence is gnd vcc scl sda. For the firmware, you can refer to the monochrome screen firmware of Tai Chi Maker. During the recording process, you need to use esp01s to burn it and then solder it on. This is the first time for beginners to do it. Please don’t complain if you are an expert!
