SiPy

The SiPy is a multi-network (Sigfox, WiFi and BLE) development platform. It is programmable with MicroPython and the Pymakr IDE for fast IoT application development, easy programming in-field and extra resilience with network failover. The best blend of speed to deployment and access to new LPWAN networks rolling out across Europe, USA, Africa and India. You can also configure the SiPy in FSK mode to send packets directly from SiPy to SiPy. This way you can create the network configuration of your choice and then use another SiPy as central Nano-Gateway to forward the data to the cloud via WiFi. Our module is CE, FCC, IC and RCM certified!

NOTE: SIGFOX CONNECTIVITY IS INCLUDED FOR 12 MONTHS FROM FIRST USE OF DEVICE FOR DEVELOPMENT UNITS. THIS DOES NOT INCLUDE LARGER DEPLOYMENTS/COMMERCIAL USE WHERE A PAYABLE SERVICE WILL BE REQUIRED. CONTACT PYCOM FOR PRICING

NOTE: Using the Sigfox radio without the external antenna can lead to damage of the device and is therefore not recommended.

If you are purchasing the SiPy and wish to connect via USB to your computer, you will also need to purchase either the Expansion Board 3.0, Pysense or Pytrack.
