1. Introduction
TTL-WiFi is designed and developed based on ESP-M2 WiFi module from our company Shenzhen
Doctors of Intelligence & Technology Co., Ltd., which is extracted the TTL, EN, STATE and other pins.
Importantly, the TTL-WiFi is already built-in the serial transparent transmission firmware programmed
by our company (SZdoit), which can realize the transparent transmit the data to the cloud on the real-time,
together with low-power control, status indictor. This board can replace the old wiring serial WiFi device
to realize the data collection and control. It has the following features.

Fully compatible with the original electrical interface and physical interface for the serial transparent
Bluetooth;

Built-in the industrial transparent transmission firmware V3.0 with stability and reliability by using
the Web Configuration;
