OVERVIEW
Circuit Description
AX−Sigfox is an ultra−low power single chip solution for
a node on the Sigfox network with both up− and down−link
functionality. The AX−Sigfox chip is delivered fully ready
for operation and contains all the necessary firmware to
transmit and receive data from the Sigfox network in
Europe. It connects to the customer product using a logic
level RS232 UART. AT commands are used to send frames
and configure radio parameters.
Features
