1. Introduction
LTM3210 Wi-Fi module provides a highly-integrated and flexible platform for developing and
evaluating products and applications based on the QCA4010 SoC.
LTM3210 module includes the following components:
■ QCA4010 chip
■ An integrated Balun to save cost and size, minimize tuning and tolerance
■ A printed antenna
■ Apple MFI (optional)
■ 2MB SPI Flash memory and etc.
The QCA4010 is a single band 1x1 802.11 b/g/n device optimized for low-power embedded
applications with single-stream capability for both Tx and Rx. It has an integrated network
processor with a large set of TCP/IP with IPv4/IPv6-based services. These services can be accessed
via a serial SPI link or by a UART link connected to an external host CPU.
