T-Beam V1.1 IPEX NEO-M8N GNSS support GPS Beidou GLONASS Module

Product Introduction

T-Beam V1.1 IPEX NEO-M8N GNSS Version, change GPS chip and LoRa antenna based on T-Beam V1.1, using Semtech NEO-M8N GNSS chip design, also support GPS Beidou GLONASS, stronger positioning signal, The positioning speed is faster; the LoRa antenna interface is changed from SMA to IPEX, which is more convenient to store.

Product upgrade changes:(Compared with V1.0）
