This is a T-Call V1.4 ESP32 Wireless Module SIM Antenna SIM Card SIM800L Module Unsoldered. The module is used for wireless communication. The ESP V1.4 ESP32 Serial WIFI Wireless Transceiver Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network.

This module has a powerful enough onboard processing and storage capability that allows it to be integrated with the sensors and other application-specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

Note : AM-036 printed on board working remains same.

Features:

  1. The SIM800L wireless communication module is integrated with an ESP32 chip with a dual-core 32-bit LX6 microprocessor.
  2. The SIM800L ESP32 wireless module needs a power supply of 5V/1A and has a Type C port.
  3. The ESP32 SIM800H wireless communication module features 802.11 b/g/n wifi protocol and Bluetooth v4.2BR/EDR and BLE standard protocol.
  4. This wireless communication module supports cloud server development and SDK for user firmware development.

Package Includes:

1 x T-Call V1.4 ESP32 Wireless Module SIM Antenna SIM Card SIM800L Module Unsoldered

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
