GNSS - GPS - GSM — buying guide

What is in this category

4 products: Ublox NEO-6M GPS Module + Antenna, Original Sim900 GPRS GSM Module + Antenna (IMEI unregistered), Ublox NEO-7M GPS/GLONASS Module + Antenna, Original Sim800L GPRS GSM Module (IMEI unregistered).

How to choose

  • NEO-6M — the classic GPS, ~1 m accuracy, UART; coordinates, speed and time with TinyGPS++.
  • NEO-7M — GPS + GLONASS, faster satellite lock, more stable in cities.
  • SIM800L — compact GSM module, SMS, calls, GPRS internet; 3.7–4.2V supply, 2A peaks.
  • SIM900 — larger module with antenna, more stable signal; Arduino shield form.
  • Both GSM modules are not IMEI-registered — activating with a local SIM in Azerbaijan may require IMEI registration.

Compatibility

Modules connect over UART (SoftwareSerial); GSM needs its own strong supply (LM2596 or Li-ion) — the Arduino 5V pin is not enough.
