  • Ultra-Small foot-print 23.3mm x 25mm (<6cm²)
  • Versatile usages, breadboard or vertical Single Inline Package
  • Simple control by AT commands
  • Sigfox verified Wisol module
  • All inclusif kit with Antenna and 1 year subscription
Made in France


Thanks to the small dimension of the SFM10R4 Wisol module, an ultra-small foot-print breakout board design was possible.

The design of the breakout allows versatile usages from the development of your prototype to the mass production of your project. Indeed, the layout of input/output pin is such that you can use the standard module features with the breakout board positioned vertically as a Single Inline Package module (SIP). Therefore, the integration into your PCB design is possible and facilitated.
