Uplynx RCZ2/4 SIGFOX Module

Tiniest Form factor for 22dBm RF Power

UPLYNX-M-RCZ24 is a Sigfox Verified modem module for the low power wide area network (LPWAN) market. It is designed with M2COMM’s system on chip M2C8001 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 23dBm or above . The design is fully compliant to FCC regulations. The Sigfox application is running on M2C8001 at high efficiency. 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.
