SIGFOX ‘Uplynx’ System on Chip

Uplynx is based on M2C8001, one of M2COMM’s family of wireless SoC designed for ultra-low-power wireless IoT applications. Uplynx monolithically integrates Sigfox protocol stack with best-in-class sub-GHz RF performance. M2C8001’s built-in 10 bit ADC, analogue comparators and GPIOs are available for access via AT command set over UART interface. Uplynx is the most cost effective, smallest, and easy-to-design SoC solution for IoT applications where wireless data uplink is enabled via Sigfox network.
