AXM22001-2A-C
IEEE 802.11b/g WiFi Module Board User’s Guide
Copyright © 2011 ASIX Electronics Corporation. All rights reserved.
The AXM22001-2A-C is a 2.4GHz 802.11b/g WiFi module
board which integrates AX22001 and Airoha AL2230S RF
transceiver on board to provide a complete WiFi module
solution with various user or host interfaces supported. The
AXM22001-2A-C is a surface mountable module with
castellated mounting holes which offers smaller-form-factor,
lower-cost, pre-calibrated RF front-end and pre-certified WiFi
module board to free the user from RF and antenna design
tasks and regulatory compliance testing, ultimately providing
quicker time to market. The user can design his host board with
desired function and interface circuits and assemble it with the
AXM22001-2A-C WiFi module board through the castellated
mounting holes.
