Also known as: LilyGo T-Beam · TTGO T-Beam · T-Beam Meshtastic · ESP32 LoRa GPS board
The go-to Meshtastic node: ESP32 plus LoRa, GPS and an 18650 holder on one board, so you can build an off-grid mesh-comms device without wiring radios yourself.

Gotchas to know
- Buy the LoRa frequency legal for your region (433 / 868 / 915 MHz): the wrong band is illegal and will not mesh with locals.
- The 18650 cell is not included; the holder takes flat-top unprotected cells.
- Revisions differ a lot (PMU went AXP192 to AXP2101, GPS NEO-6M to M8N/M10, Micro-USB to USB-C), so match any guide to your exact board.
- The OLED is optional; some kits ship without a screen.
Variants
The classic T-Beam v1.1 is ESP32 (SX1276/1262, NEO-6M/M8N). The newer T-Beam Supreme is ESP32-S3 with an SX1262 radio and NEO-M10S GPS.
The ESP32 inside
This board is built on the ESP32 (ESP32 (classic)). See the SoC page for the full peripheral, GPIO and security details.
