LILYGO LORA32 T-Beam ESP32 SoftRF Development Board WiFi BLE CH9102F Chip TTGO OLED Module

Product description Due to the discontinuation of AXP192, it has now been replaced by AXP2101. Add reverse battery protection module This product is factory burned SoftRF firmware. The programming is slightly different, please refer to Github github. com/Xinyuan-LilyGO/LilyGO-T-Beamfor details! Pin Map 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.
