Product Parameter

T-Beam is a low-power development board that integrates ESP32, LoRa, and GPS and supports Wi-Fi Bluetooth short-range LoRa long-distance communication functions.
T-Beam IPEX NEO-M8N GNSS Version, change GPS / LoRa chip and LoRa antenna based on T-Beam .
LoRa chip using Semtech SX1262 LoRa RF transceiver chip design, works in the 868/915MHz ISM frequency band, integrates a highly stable TCXO 32MHz crystal oscillator, half-duplex transceiver module, power up to +22dBm, too -139dBm receiving sensitivity.
The LoRa antenna interface is changed from SMA to IPEX, which is more convenient to store.
GPS chip using Semtech NEO-M8N GNSS chip design, also support GPS Beidou GLONASS, stronger positioning signal, The positioning speed is faster.

If GPS doesn't work, you may encounter the following situations:

Install meshtastic firmware before, and now reset the GPS when u change to another firmware.

reset steps :github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/tree/master/firmware/GPS_%20reset_test

When GPS is weak indoors, it can be used outdoors
The GPS antenna is not installed stably, you can check whether the interface is fastened to the GPS antenna

The CH9102 serial port programming chip is convenient for daily programming. Before connecting, you need to pay attention to ensure that the driver has been installed on the compute. Use 3D wifi antenna to save space,we also reserved IPEX antenna base for use.[Note that the onboard antenna and external antenna can't be used together. Onboard ESP32 MCU with WiFi BLE [v4.2] transmission function, 4MB Flash and 8MB PSRAM, supporting daily entry-level programming. The built-in SX1276[915mhz] Lora chip facilitates the project to send and receive data over a long distance with low power consumption. This version does not have soldered OLED screens.
