Vszerda TTGO Meshtastic T-Beam V1.2 ESP32 LoRa GPS Development Board 915Mhz OLED Display

SKU CH-GYNH-5EATK

ESP32 LoRa GPS development board with OLED display operating at 915 MHz

  • ESP32 core enables rapid IoT prototyping
  • LoRa at 915MHz gives long-range mesh links
  • On-board GPS adds location data to messages
  • 2-inch OLED shows status without a PC

LoRa development board with GPS and OLED

The Vszerda TTGO Meshtastic T-Beam V1.2 integrates an ESP32 microcontroller with a 915 MHz LoRa transceiver and built-in GPS receiver. An on-board OLED display provides immediate visual feedback for configuration and message status. The board targets makers and researchers building long-range mesh networks or remote sensor nodes that operate beyond conventional Wi-Fi or cellular coverage.

Sustained operation in remote deployments

During continuous transmit cycles the ESP32 and LoRa radio draw steady current that can stress small batteries or solar chargers not sized for the duty cycle. The GPS module adds further load when acquiring a fix in weak-signal environments. Projects requiring weeks of unattended runtime must plan power budgets carefully rather than relying on brief benchmark figures. Buyers needing integrated battery management or lower-frequency bands should evaluate alternative hardware.

Questions about this item

How much heat does the 915 MHz LoRa radio add when the T-Beam V1.2 runs Meshtastic continuously?

The board stays cool during long Meshtastic sessions because the LoRa transceiver and ESP32 draw very little current at idle.

What extra hardware is required to start using the GPS on this ESP32 board?

Only a USB cable for power and flashing; the GPS antenna is already integrated on the PCB.
