Overview

Meshtastic Mesh Device Station G2 is an upgraded design of Station G1, using the latest ESP32 S3 MCU. As an RF research project, Station G2 also brings key updates in RF. The primary RF design goal of Station G2 is to improve the Lora receiving sensitivity by about 4dB based on a dedicated Ultra-Low Noise Figure LNA. And to increase the transmit power and improve Signal to Noise ratio of short data packets by designing the Fast-Transient DC-DC for 35dBm Lora PA.

For Lora Power Amplifier, the 1 dB Compression Point (P1dB) is 35 dBm (3.16 W), and the maximum RF output power is 36.5 dBm (4.46 W) for US915 and 37 dBm (5 W) for EU868.

Station G2 has a rugged SMA antenna socket and rich external IO interfaces. It can be powered by either 15VDC USB Type C PD protocol or 9VDC-19VDC External Power Supply. These features make Station G2 ideally suited as a Fixed-Location Base Station or Vehicle-Mounted Base Station.
