OVERVIEW
Circuit Description
AXSFEU and AXSFEUAPI are ultralow power
single chip solutions for a node on the Sigfox network with
both upand downlink functionality. The AXSFEU 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.
The AXSFEUAPI variant is intended for customers
wishing to write their own application software based on the
AXSFLIB1GEVK library.
Features
Functionality and Ecosystem
Sigfox uplink and downlink functionality controlled
by AT commands or API
The AXSFEU and AXSFAPI ICs are part of a
whole development and product ecosystem available
from ON Semiconductor for any Sigfox requirement.
