Station G
Station G2
The Station G2 is a fixed LoRa device by Station G, based on the ESP32-S3 microcontroller and the SX1268 LoRa transceiver. It transmits at up to 30 dBm with -148 dBm receive sensitivity and draws about 110 mA on average. It is compatible with Meshtastic and MeshCore.

How long does a Station G2 last on battery?
At about 110 mA average draw, a Station G2 runs roughly 1.1 days on a 3000 mAh 18650 cell and 3.8 days on a 10000 mAh pack. Real-world life depends on transmit duty cycle, screen and Bluetooth use.
What is the range of a Station G2?
With the stock 2.15 dBi antenna at 5 m, the theoretical line-of-sight range is about 14.3 km. In practice terrain and obstacles reduce it; raising the antenna is the single most effective improvement.
Is the Station G2 good for a solar node?
It can work, but at ~110 mA average draw it needs a bigger panel and battery than nRF52840-based boards (≈12 mA).
