Station G2 Setup Guide

⚠ ANTENNA SAFETY - ALL DEVICES: Always connect an antenna before powering on any LoRa device.
Even a brief transmission without an antenna connected risks permanent damage to the LoRa radio chip.
 

 Station G2 - Setup Guide 
 The Station G2 is a purpose-built fixed base station with the highest available TX power of any
standard LoRa node (36.5 dBm / 4.5 W) and an integrated LNA for excellent receive sensitivity.
It is designed for hilltop, tower, and infrastructure deployments - not personal portable use. 

 Specifications 
 
 Attribute Value 
 MCU ESP32-S3 
 Radio SX1262 + power amplifier + LNA 
 Max TX Power 36.5 dBm (4.5 W) 
 Price $109 
 Strengths Highest TX power, integrated LNA, purpose-built for fixed infrastructure 
 Weaknesses Expensive; requires high-voltage power; overkill for personal use 
 

 
 ⚡ CRITICAL POWER REQUIREMENT: 
 The Station G2 requires 15V USB-C Power Delivery (PD) or 9 - 19V external DC 
 (5.5×2.1 mm barrel jack). The high-power amplifier cannot operate at standard 5V. 
 Standard 5V USB will NOT power the Station G2. 
 Use one of:
 
 A USB-C charger that supports Power Delivery (PD) at 15V - verify PD capability before purchasing 
 A 12V DC supply via the 5.5×2.1 mm barrel jack (9 - 19V range accepted) 
 
 Connecting only 5V will result in the device appearing to power on but the RF amplifier will not function.
 

 Driver Installation 
 
 Windows: CP210x driver may be needed. Download from Silicon Labs website if device is not detected. 
 macOS & Linux: Built-in - no driver needed. 
 

 Entering Bootloader / DFU Mode 
 Method 1 - From powered-off state: 
 
 Disconnect power. 
 Hold the BOOT button. 
 Connect USB while holding BOOT. 
 Release BOOT after ~2 seconds. 
 
 Method 2 - From powered-on state: 
 
 Hold BOOT . 
 Briefly press and release RST . 
 Release BOOT. 
 

 Firmware Flashing 
 
 Enter bootloader mode. 
 Open Chrome or Edge and navigate to:
 
 MeshCore: flasher.meshcore.io 
 Meshtastic: flasher.meshtastic.org 
 
 
 Select Station G2 from the device list. 
 Click Flash . Do not disconnect during flashing. 
 

 Post-Flash Configuration 
 MeshCore: 
 
 Configure via Bluetooth or serial connection. 
 Set region to US . 
 High power output is available - configure carefully to remain within FCC EIRP limits for your antenna gain. 
 For most infrastructure deployments: use an external directional or high-gain antenna. 
 
 Meshtastic: 
 
 Set role to Router in the app for infrastructure deployment. 
 Configure power settings and region. 
 Consider EIRP limits when selecting antenna gain. 
 

 Known Quirks & Deployment Notes 
 
 Power supply verification is essential - confirm PD output voltage before connecting. 
 At 4.5 W TX power, antenna quality and coax loss matter significantly. Use low-loss coax and quality connectors. 
 EIRP (Effective Isotropic Radiated Power) limits apply - high-gain antennas may require reducing TX power to stay legal. 
 Ideal placement: hilltop, water tower, or rooftop with clear line-of-sight horizon.
