Description
Product upgrade changes: 1. Add reverse battery protection module ?More information: https://github.com/Xinyuan-LilyGO/LilyGO-T-Beam Product Features:T-SX1262 wireless transceiver module, 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, to -139dBm receiving sensitivity. Automatic switching of sending and receiving, isolation of internal sending and receiving channels, advanced LORA spread spectrum communication technology, with strong anti-interference and privacy, can realize long-distance wireless data sending and receiving.
