TTGO T-Beam V1.1 ESP32 LORA 868MHz WiFi Wireless Bluetooth Module with IPEX &18650 Battery Holder-Unsoldered

The TTGO T-Beam provides a comprehensive set of features through its 26-pin headers. These include GPIO, ADC, VP/VN, DAC, touch, SPI, I2C, UART, 2דLoRa” pins, and power signals (5V/3.3V/GND). The GPIO39 pin of the ESP32 is also accessible via the second button on the board, in addition to the power button. This versatile configuration allows for a wide range of functionalities and interfaces, making the TTGO T-Beam a flexible and powerful development board.

The board is built around a dual-core ESP32 chip, with 4MB of SPI flash onboard, providing both Wi-Fi and Bluetooth LE via a “3D antenna” on the PCB. The board’s LoRa support comes in three different variants, operating at 433MHz, 868MHz, and 915MHz depending on region, with an included SMA antenna. While location tracking is provided by the onboard u-Blox NEO-6M GPS module with a ceramic antenna.

The board can be programmed using the Arduino development environment, and the example code shows you how to both send and receive data via LoRa.Flipping the board over there is a battery holder for a 18650 Li-Ion cell, and while a 18650 sort of looks like a “standard” AA battery, it’s significantly different. So don’t make the mistake of substituting in the more common AA battery to try and power the board. They’re not quite the same size, but I’ve seen people attempt this substitution nonetheless.
