High power notes

MigrationHigh power units include the Station G2 and Portduino units (30dB)

Station G2:

  • esp32-s3 chip
  • includes wifi, but disables BLE when active
  • monitoring screen with FW 2.7 has many display options
  • 30 dB power amplifier (need to reduce input power from the ESP32 chip to 19 dB to decrease noise and reduce overloading)
  • sensitive preamp beyond -145dB
  • powered by usb-c (just the chip) and usb-c PD 20W for power amplifier to work
  • can also be powered by 12V with 5 pin connector
  • can be hand carried with external power supply
  • excellent base station option
  • can be seen by meshsense on BLE or wifi if enabled
Portduino:
  • portduino is an arduino port running on a raspberry pi using meshtasticd, a linux program
  • using a meshadv HAT (add on to a raspberry pi) with an ES22 chip (30dB RF output)
  • advantages over G2: 
    • ethernet access
    • can run meshtasticd and meshtastic
    • can host a meshsense app, or remote to another server
    • good for a base station if you already have a pi, know linux and terminal
  • disadvantages:
    • more DC power required
    • cooling is an issue
    • uses a Pi, which is not cheap (around $75) along with a meshadv HAT (another $75)
    • no preamp like on the G2
  • other options:
    • waveshare HAT (has CRC issues, so can only be used in progressclient formute mode)
    • not high power, but can be POE linked using appropriate HATs
    • can run on pi zero: low power, cheaper ($25)
    • cheaper chip
    • can include GPS
