【Function】Onboard ESP32 MCU with WiFi Ble v4.2 transmission function, 4MB Flash and 8MB PSRAM, supporting daily entry-level programming | 【Lora Chip】The built-in SX1276（915MHz）Lora chip facilitates the project to send and receive data over a long distance with low power consumption | 【GPS】GPS NEO-6M module, with RCT clock battery, and equipped with mini ceramic antenna for daily positioning | 【Antenna】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） | 【Programming】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

【Github】github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series | 【Feature】Add the SMA and TP4054 to the board,which make it can do more things | 【Advantage】In terms of the power switch, we have changed the switching interaction mode,SMA antenna can enhance signal transmission | 【Paxcounter】Paxcounter is an ESP32 MCU based device for metering passenger flows in realtime. It counts how many mobile devices are around. This gives an estimation how many people are around | 【Data transmission】Data can either be be stored on a local SD-card, transferred to cloud using LoRa WAN network or MQTT over TCP/IP, or transmitted to a local host using serial (SPI) interface
