Sigfox WSSFM11R3AT module from Seong Ji - Wisol

Sigfox WSSFM11R3AT module from Seong Ji - Wisol

Region 3 (Japan RC3c) SigFox module from Korean manufacturer Wisol Seong Ji, reference SFM11R3 or WSSFM11R3AT.

This module will allow you to integrate and use the SigFox LPWan network in your IOT project design, offering a very simple data transmission functionality.

Ultra-Small foot-print 13mm x 15mm x 2.21mm Simple control by AT commands Sigfox Verified certified module

Thanks to its small size, the Wisol SFM11R3 module allows a very small board design compared to the existing Sigfox modules on the market.

The SigFox network allows sending 12 bytes messages long. The Sigfox network is nationaly available in many European countries. Please check the coverage here :  http://www.sigfox.com/en/coverage
