== Summary ==
The Pico-SIM7080G is an NB-IoT/Cat-M/GNSS module for the Raspberry Pi Pico. It supports global frequency bands, AT commands over UART, and HTTP/MQTT as well as GNSS positioning.

== Technical overview ==
* Connects via standard Pico header; UART communication with serial AT commands.
* Supported protocols: TCP/UDP/HTTP/HTTPS/TLS/DTLS/PING/LWM2M/COAP/MQTT.
* GNSS systems: GPS, GLONASS, BeiDou, Galileo.
* NB-IoT data rates: 136 Kbps (DL) / 150 Kbps (UL).
* Cat-M data rates: 589 Kbps (DL) / 1119 Kbps (UL).
* Power: external LiPo battery or Pico USB port; battery interface 3.7–4.2 V.
* Logic level: 3.3 V.
* Two LEDs: NET (network status) and Charge (charging status).
* SIM slot accepts only 1.8 V SIM cards; 3 V cards are not supported.

'''Commands and examples – verify before use:''' 
<syntaxhighlight lang="text">
AT+CMNB=2 // Fix NB-IoT mode
AT+CMNB=1 // Fix Cat-M mode
AT+CNMP=38 // Fixed LTE mode for faster network registration
AT+CPSMS=1 // Enable PSM low-power mode
AT+CPSMS=0 // Disable PSM mode
</syntaxhighlight>

== Notes and version constraints ==
* Simultaneous use of cellular network and GPS positioning is not possible according to the source.
* If there is no signal: fixing the mode (NB-IoT or Cat-M) makes registration easier.
* Communication failures may be caused by poor hardware contact; certain solder points must be soldered, especially 3.3 V.
* The AT commands listed come from the AT manual; parameters may differ across firmware versions – verify before deployment.
* No information on prices, stock, certifications, or warranty was provided in the source material.
