T18-Energy Bluetooth and Wi-Fi Ver3.0 Module with ESP32 Processor

The T-ENERGY TTGO Module, part of the TTGO board series, features the T-Energy Bluetooth and Wi-Fi Module with ESP32 Processor and includes a built-in 18650 battery holder. The ESP32 chip, developed by Espressif, is the newer, well-known successor to the ESP8266, offering both Wi-Fi and integrated Bluetooth connectivity. It boasts very low power consumption, an excellent design, and delivers strong performance in industrial environments.

The ESP32 chip includes built-in Bluetooth and Wi-Fi, a 32-bit Tensilica Xtensa LX6 processor running at 240 MHz with a performance of 600 DMIPS, and supports an Ultra Low Power Co-Processor. This allows you to read analog values via its ADC even in Deep Sleep mode.

The T-ENERGY Bluetooth and Wi-Fi Module on the T-ENERGY TTGO Module provides multiple common communication ports such as UART, I2C, ADC, SPI, and DAC. Additionally, an onboard LED indicates charging status and module operation.

Applications of the T-Energy Bluetooth and Wi-Fi Module

1. Internet of Things (IoT) projects
2. Portable electronic devices
