elegance and simplicity by design

Introducing

The Universal IEEE 802.15.4 Sensor for WSN and IoT applications

"After using several developing boards, we needed a more complete and versatile solution, small, flexible but still simple and cost-effective..."

Model S2 based on Atmel AtMega256RFR2 is a proven and robust design.

Built on high quality components and used in several projects and courses.

Contiki support for the platform (avr-rss2)
