Uplynx Sigfox VerifiedTM RCZ1 Module

Tiny Form factor, Easy integration

UPLYNX-M-RCZ1 is a Sigfox VerifiedTM modem module for the low power wide area network (LPWAN) market. It is designed with M2COMM’s system on chip M2C8001 for the European market (EN 300 220). The module was designed for high performance, high quality, low cost and small form factor. The design is fully compliant to ETSI regulations. The Sigfox application is ported over M2C8001 and execute at high efficiency using its internal 32bit core 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.
