## Restrictions

**For use in Australia**

- Operate only in bands and with settings that are permitted for your location and application. Check this product’s supported frequencies in the description/specs.
- If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation.
 
**For use in other regions**

- Follow the spectrum rules for your country/region and select frequencies and settings accordingly.

A declaration of use will need to be submitted during checkout.

## Description

The LoPy4 is a compact quadruple network MicroPython enabled development board (LoRa, Sigfox, WiFi, Bluetooth). It’s the perfect enterprise-grade IoT platform for your connected Things. With the latest Espressif ESP32 chipset the LoPy4 offers a perfect combination of power, friendliness, and flexibility. Create and connect your things everywhere. Fast.

The LoPy4 can act as a LoRa nano gateway and a multi-bearer (LoRa, Sigfox, WiFi and BLE) development platform suitable for all LoRa and Sigfox networks around the globe. It is programmable with MicroPython and the Pymakr plugins for fast IoT application development, easy programming in-field and extra resilience with network failover. You can also configure the LoPy4 in raw LoRa mode to send packets directly between LoPy4’s. The best blend of speed to deployment and access to new LPWAN networks rolling out across Europe, USA, Africa and India. The LoPy4 is CE, FCC approved, LoRaWAN and Sigfox certified.

Some handy notes:

- The LoPy4 includes 1 year of Sigfox connectivity.
- Using the LoRa or Sigfox radio without the external antenna can lead to damage of the device and is therefore not recommended.
- [Update the firmware](https://docs.pycom.io/gettingstarted/installation/firmwaretool) before use (Pycom have made a great utility to easily manage firmware updates)
 
If you are purchasing the LoPy4 and wish to connect via USB to your computer, you will also need to purchase either the Expansion Board, Pysense or Pytrack.
