This esp32 sim800l wireless communication module. The wireless module is equipped with an ESPRESSIF-ESP32 dual-core 32-bit LX6 CPU running @ 240MHz. This communication module requires a Type C connector and a 5V/1A power source. It has Bluetooth v4.2BR/EDR and BLE standard protocol, as well as 802.11 b/g/n wifi protocol.
The cloud server development and SDK for user firmware development are both supported by the wireless communication module. This wireless communication module is compatible with the SIM800L GPRS Module. This communication module may also be used as a development board for the ESP32 (ESP-ROVER-B 8MB PSRAM). UART, SPI, SDIO, I2C, LED PWM, TV PWM, I2S, IRGPIO, capacitor touch sensor, ADC, DACLNA pre-amplifier module interface are all used in this wireless module. It uses a 2.7V-3.6V operating voltage and accepts a Nano SIM card. The ESP32-based wireless communication module, on the other hand, is ideal for IoT applications. Because it’s a USB Type C pluggable board with a LiPo Battery Charging Circuit and Connector aboard.
The SIM800L GSM/GPRS module, which is a small GSM modem, may be used in a variety of IoT projects. This SIM800L GSM/GPRS module works in the same way as a regular cell phone. It can send and receive SMS text messages, make and receive phone calls, and connect to the internet through GPRS and TCP/IP, among other things. Furthermore, the module supports a quad-band GSM/GPRS network, indicating that it may be used almost anywhere on the planet.
