ماژول ESP-800L با رابط TTL , UART

این ماژول SIM800L بوده و سازگاری کامل با پایه های ESP8266 دارد. مدار از 5 ولت به جای 3.3 ولت استفاده می کند.

Introduction

This module SIM800L GPRS GSM is one of the smallest and most powerful on the market, it has an input for SIM800L chip (cell phone chip), it works with voltages from 3.7V to 4.2V. Supports network connection: China Mobile, China Unicom and the global quad-band network.  The module has a TTL serial port, it can be connected directly to the micro controller, MAX232 is not required. When you turn on the module, it automatically starts by connecting to the established startup network. The card has signal lights for all routes, when it produces slow flashes it means that there is a signal, however when it produces rapid flashes it means that there is no signal.
