Sigfox is a global low power wireless network offering service in over 65 countries including the US, and Canada.  Now is the time to start learning what the Sigfox "0G Network" can offer for IOT use cases that require low cost and 2-10 years of battery life.   Initial Feather Wing boards will support the US, Canada, Mexico and Brazil regions. This Feather Wing includes a complementary 1 year subscription  to the Sigfox "0G Network" and FREE activation.  The FCC certified radio module is programmed via AT Command interface -- 1 line of code is all you need to send a Sigfox message.  On-board sensors from ST Microelectronics and Avago Technologies are connected to the host Feather via I2C and come with example code and descriptions on how to forward sensor data via Sigfox Cloud APIs and Callbacks Popular asset tracking use-cases are well adapted to the ESP32 HUZZAH Feather with BLE and WIFI radios.  BLE Beacon sniffing  combines with outdoor WIFI-based geolocation (and GPS) match perfectly with the Sigfox payload arrangement.  

Coverage concerns?   Sigfox has dense coverage in many of the major cities in North America.  To augment local coverage, Digi-Key now offers the Sigfox Access Station Micro.
