Ultra-Low Power, AT Command / API Controlled, Sigfox Compliant Transceiver IC for Up-Link and Down-Link

Topology: Other


AX−SFEU and AX−SFEU−API are ultra−low powersingle chip solutions for a node on the Sigfox network withboth up− and down−link functionality. The AX−SFEU chipis delivered fully ready for operation and contains all thenecessary firmware to transmit and receive data from theSigfox network in Europe. It connects to the customerproduct using a logic level RS232 UART. AT commands areused to send frames and configure radio parameters.The AX−SFEU−API variant is intended for customerswishing to write their own application software based on theAX−SF−LIB−1−GEVK library.
