This module is a wireless communication module that connects any microcontroller to your WiFi network via the ESP V1.4 ESP32 Serial WIFI Wireless Transceiver Module. The ESP32 module is a self-contained SOC with a built-in TCP\/IP protocol stack.<\/p>\n<p>Because of its solid inbuilt processing and storage capabilities, this module can be quickly connected with sensors and other application-specific devices, with little programming and runtime loading.<\/p>\n<p>The TTGO T-Call combines an  and a SIM800L GSM\/GPRS module. This combo offers wireless communication via the ESP32&#8217;s WiFi and Bluetooth capabilities, as well as the SIMCom SIM800L GPRS module. Notably, the board&#8217;s power and programming ports are USB-C rather than micro USB.<\/p>\n<p>Whether you need to get warnings when someone enters your room or remotely water your plants, the ESP32 with SIM800L GSM\/GPRS Module can prove quite useful. The SIM800L&#8217;s tiny size and adaptability make it an excellent choice for a variety of IoT projects.<\/p>\n<h2>Why is this Wireless Communication Module best for IoT applications?<\/h2>\n<p>The ESP32-based wireless communication module is best for IoT applications because it consists of a USB Type C pluggable board that has an onboard LiPo Battery Charging Circuit &amp; Connector.<\/p>\n<h2>Features:<\/h2>\n<ul>\n<li>The ESP32 chip, which has a dual-core 32-bit LX6 CPU, is coupled with the SIM800L wireless communication module.<\/li>\n<li>It has a Type C connector and requires a 5V\/1A power source.<\/li>\n<li>This module supports Bluetooth v4.2BR\/EDR and BLE standard protocol in addition to 802.11 b\/g\/n wifi.<\/li>\n<li>The SDK for user firmware development and cloud server development is supported by this wireless communication module.<\/li>\n<\/ul>\n<h2>Applications:<\/h2>\n<ul>\n<li>IoT Data Monitoring.<\/li>\n<li>Remote Sensing.<\/li>\n<li>Security Systems.<\/li>\n<li>Smart Home Automation.<\/li>\n<li>Environmental Monitoring.<\/li>\n<li>Asset Tracking.<\/li>\n<li>Remote Control Systems.<\/li>\n<li>Emergency Response Systems.<\/li>\n<li>Fleet Management.<\/li>\n<li>Industrial Automation.<\/li>\n<\/ul>\n<h2>Pinout:<\/h2>\n<div style=\"text-align: center;\"><img decoding=\"async\" alt=\"Pinout of&amp;nbsp;TTGO T-Call V1.4 ESP32 SIM800L Wireless Communication Module\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0559\/1970\/6265\/files\/Capture_5df63ca7-2b29-43f4-8ae9-656052282967_480x480.png?v=1701438432\" style=\"margin-bottom: 16px; float: none;\"\/><\/div>\n<h2>Package Includes:<\/h2>\n<ul>\n<li>1 x\u00a0TTGO T-Call V1.4 ESP32 Wireless Communication Module<\/li>\n<\/ul>\n<h2>Specifications:<\/h2>\n<table border=\"3\" data-mce-style=\"height: 637px; border-color: #000000; margin-left: auto; margin-right: auto; width: 546px;\" style=\"height: 637px; border-color: #000000; margin-left: auto; margin-right: auto; width: 546px;\">\n<tbody>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Chipset<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">ESPRESSIF-ESP32 240MHz Xtensa\u00ae dual-core 32-bit LX6 microprocessor<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">FLASH<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">QSPI flash 4MB \/ PSRAM\u00a0 8MB<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">SRAM<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">520 kB SRAM<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Modular interface<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">UART, SPI, SDIO, I2C, LED PWM, TV PWM, I2S, IRGPIO, capacitor touch sensor, ADC, DACLNA\u00a0 pre-amplifier<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">SIM card<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">Only supports Nano SIM card<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Power Supply<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">USB 5V\/1A<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Wifi Protocol\u00a0<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">802.11 b\/g\/n<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Communication distance<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">300m\u00a0<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Bluetooth Protocol\u00a0<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">Bluetooth v4.2BR\/EDR and BLE standard<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Dimensions\u00a0<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">78.83mm x 28.92mm x 8.06mm<\/td>\n<\/tr>\n<tr>\n<td data-mce-style=\"width: 276px;\" style=\"width: 276px;\">Weight\u00a0<\/td>\n<td data-mce-style=\"width: 250px;\" style=\"width: 250px;\">12 grams<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>TTGO T-Call V1.4 ESP32 SIM800L Wireless Communication Module You&#8217;re looking at an unsoldered TTGO TCall ESP32 SIM800L module with a SIM antenna and SIM card slot.
