Sigfox EVB Board WSG300S

WSG300S Sigfox Verified Module (RC2/4)
RF Output Power Up To +22dBm (Sigfox)


WSG300S RC24 is a Sigfox modem module for the low power wide area network (LPWAN) market. It is designed with STM’s
system S2-LP+STM MCU+Sky66421 for the US or other FCC-like market (FCC Part 15.247). The module was designed for high
performance, high quality, low cost, small form factor and most importantly, high RF power of up to 22dBm. The design is fully
compliant to FCC regulations. The Sigfox application is running on STM32 MCU at high efficiency using its internal 32bit core
Cortex-M0 processor. Every module is preloaded with Sigfox application software, module specific ID/KEY/PAC as referring to
Sigfox network system. The preloaded software also includes a bootloader which allows software update or future user
application development.
