Station Series

The Station series of devices, designed by Neil Hao from B&Q Consulting and powered by Meshtastic, are compact and durable LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. devices designed for high-performance radio frequency communication. They feature a powerful PA for LoRaLoRaA low-power, long-range wireless communication technology used by Meshtastic devices to enable communication over distances of several kilometers without the need for cellular, Wi-Fi, or other traditional network infrastructures. communication, a rugged SMASMAA threaded coaxial connector for attaching an external antenna. RP-SMA is the reverse-polarity variant, which is not interchangeable with it. antenna socket, and a variety of external IO interfaces.

Station G3​

Station G3

The Station G3 is modular. A motherboard carries a separate MCU daughterboard and RF daughterboard, so each can be replaced or upgraded on its own. The MCU socket follows the Raspberry Pi 40-pin GPIO layout, so a Raspberry Pi Zero 2 W can take the place of the ESP32-S3 daughterboard and run meshtasticd, the Meshtastic daemon for Linux.

Specifications​

  • MCU
    • ESP32-S3 (16 MB flash, 8 MB PSRAM) on the BQESP32V1M daughterboard
      • Wi-Fi
      • Bluetooth 5.0
  • LoRa Transceiver
    • Semtech SX1262 on the BQ35LORA900V1M daughterboard
    • LoRa Power Amplifier
    • Low-noise amplifier (LNA) with dynamic gain control, which a jumper can disable
  • Frequency options
    • 850 - 930 MHz
  • Navigation Module
    • Optional (1x GROVE GPS Socket)
  • Antenna
    • SMA Socket
  • Connectors
    • USB-C (15 V PD) or DC5521 barrel jack (9 V - 19 V), on the motherboard
    • USB-C on the MCU daughterboard, for data only

Features​

  • 1.3 inch OLED screen
  • User button
  • Four jumper-set power levels, from about 31 dBm (default) to 34 dBm (boost) on Meshtastic firmware
  • GROVE I2C Socket
  • GROVE GPS Socket
  • Raspberry Pi compatible 40-pin MCU daughterboard socket
  • Power good checker LEDs

The power supply must provide at least 25 W, and must not exceed 19 V. Power Level 4 requires at least 10 V.
