ESP01S-0.96OLED display

Use ESP01 or 01s, and a 0.96 IIC OLED screen. Pay attention to the OLED pin sequence of this PCB. Some pin sequences are different from mine, so be sure to pay attention! ! ! Be sure to pay attention! ! ! Be sure to pay attention! ! !

You can refresh station B fan display or weather clock.

GPIO0 and GPIO2 have been connected to two independent buttons. The IIC interface uses RXD (GPIO3) and TXD (GPIO1). These two pins need to be designated as IIC pins in the program.

The download program needs to be downloaded through the serial port downloader, and then the ESP01S is connected to the PCB.

ESP01/01S has four IO ports available, IO2 IO0 RXD (GPIO3) TXD (GPIO1). Under normal circumstances, IO1 and 3 are used for serial port downloading, but they can also be used for ordinary IO. IO0 needs to be used when downloading programs through the serial port. Manually pull down to enter download mode.

P1 is the battery power supply interface and does not need to be welded.

The side button does not need to be installed.

The ESP01S module is soldered directly to the PCB without a socket.

This product is flashed with the firmware controlled by the up master of Station B. I modified the pin definition myself. Link: https://www.bilibili.com/video/BV1WC4y1h7k4/?spm_id_from=333.788.recommend_more_video.-1.
