ESP-12F_Maker Card

Overview

# ESP-12F card-type development board

Introduction

I just finished the final design of stm32 recently. Since the price of stm32 has increased seriously now, I want to play with the ESP series. I made an ESP-01S OLED electronic clock on a perforated board. I feel that it is not comfortable to use the module, so I want to make one. board. First of all, this board must be an ESP8266 development board. Secondly, it must have an OLED screen. Finally, consider making it into a card, which can also be used as a small gift for the students in the laboratory.

Burning matters

When burning the program, you need to press RST once to restart while holding down the BOOT button. After restarting, make sure to keep pressing the BOOT button, and wait until the program burning is completed before releasing it. After burning, restart once before running the burned-in program.
