LILYGO TTGO T-Beam V1.1 ESP32 WiFi Module overview
The LilyGO TTGO T-Beam V1.1 is an ESP32 development board with 4 MB Flash that uses the EPS32 chip directly. It integrates:a a SemTech SX1276 or SX1278 for LoRaWAN communication and an U-Blox Neo-6M GPS receiver. LILYGO TTGO T-Beam has a wide variety of operational modes broken out between different GPIO pins. Since many GPIOs are broken out, they can be used for different purposes in different applications. For flexibility, some GPIOs might be listed in various peripheral configurations.
