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.
NOTE: The LoPy4 includes 2-years of Sigfox connectivity.
NOTE: Using the LoRa or Sigfox radio without the external antenna can lead to damage of the device and is therefore not recommended.
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 2.0, Pysense or Pytrack.

- How to Build Internet-Connected Electronics Projects
What do we mean when we talk about the "Internet of Things"? Mostly we're talking about tiny computers that have access to the internet and do some useful work. Unlike the computers we're used to holding in our hands, they don't have a touchscreen an...
- Pycom Bluetooth
Bluetooth is a low-power radio technology used to link devices wirelessly. Most commonly recognised as the way to link a mobile phone to a car or speaker, it has many uses beyond that. The "low power" aspect is not a shortcoming, as a large proportio...
- Pycom LoPy Overview
The two main standards at work in the low-power long-range radio game are LoRa and Sigfox. I discussed Sigfox in the Pycom SiPy Overview so I won't do that again here. The Pycom LoPy is the device that adds LoRa technology to the basic features seen ...
