SiPy - Sigfox, WiFi, BLE


I found very interesting device. It combines all of popular wireless technology.

SiPy. The device is based on ESP32, for faster development of your project.

It combines wireless technology like WiFi, BLE (Bluetooth Low Energy) and Sigfox which is used for IoT (Interent of Things).

Maybe you know kickstarter campaign LoPy, that's better and powerful brother of that.
