Web business card ESP8266

Please see the code documentation for the latest hardware details.
At present, the speed is comparable to that of the general ESP8266 module. For detailed test data, please see the code document.

Introduction

1. PCB thickness 1mm.
2. Code address: Github , code cloud

At present, the short-range speed is relatively close to that of the ESP-12F V3 development board. The test page speed is only 100ms different, and the long-range advantage is relatively large.
Consider optimizing Flash to further increase speed and beyond.

The current speed is 1/2 that of the ESP-12F V3 development board, and only L1 needs to be welded. However, I am still guessing. I bought a network analyzer and still haven’t figured out the rules.

The current antenna speed is 1/3 of the ESP-12F V3 development board.
The problem has been found to be the impedance matching of the PCB antenna. Jialichuang does not support impedance matching and can only modify the inductor and capacitor.
I will try to optimize the speed of the antenna as much as possible, and if I can't find suitable components, plan to use a ceramic antenna instead.
