ESP32 T-Energy WROVER-B 8M WiFi & BLE Module With 18650 Holder T18 V3.0 TTGO

AED 78.75



18650 Battery LILYGO® TTGO T-Energy ESP32 8MByte PSRAM WiFi Bluetooth Module Development Board with the ESP32-WROVER-E
The ESP32 is an updated version of the ESP8266, a chip that surprised experimenters. In several ways, the ESP32 improved on the ESP8266 design. It has Bluetooth and BLE (Bluetooth Low Energy), whereas the ESP8266 only has WiFi (which, of course, the ESP32 also has). It is faster and comes in a dual-core configuration. It can also operate in an ultra-low-power mode, making it ideal for battery-powered applications. With this board and the 18650 battery Holder attached to the back of the board, your project will be powered for an extended period depending on the battery capacity you use.


Package Includes:

  • 1 x ESP32 WROVER development board
  • 2 x Pin headers



  1. Dual-Core Performance: The ESP32-WROVER-E boasts a 240MHz Xtensa® single-/dual-core 32-bit LX6 microprocessor, offering enhanced processing power for your projects.
  2. Expanded Memory: With QSPI 4MB Flash and 8MB PSRAM, this module provides ample storage for your applications, enabling more complex and feature-rich projects.
  3. Bluetooth and BLE: Unlike its predecessor, the ESP32 supports Bluetooth and BLE (Bluetooth Low Energy), expanding connectivity options for your devices.
  4. Ultra-Low-Power Mode: The ESP32 can operate in an ultra-low-power mode, making it ideal for battery-powered applications. When paired with the included 18650 battery holder, your project can run for an extended period, depending on the battery capacity.
