YL1023
IEEE 802.11a/b/g/n/ac Wireless LAN and Bluetooth Combo Stamp Module
1. General Description
The YL1023 IEEE 802.11 a/b/g/n/ac SDIO Wi-Fi with Bluetooth 4.2 combo
stamp module is a highly integrated wireless local area network (WLAN)
solution to let users enjoy the digital content through the latest
wireless technology without using the extra cables and cords. It
combines with Bluetooth 4.2 and provides a complete 2.4GHz Bluetooth
system which is fully compliant to Bluetooth 4.2 and v2.1 that supports
EDR of 2Mbps and 3Mbps for data and audio communications. It enables
a high performance, cost effective, low power, compact solution that
easily fits onto the SDIO and UART stamp module.
Compliant with the IEEE 802.11a/b/g/n/ac standard, YL1023 uses Direct
Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division
Multiplexing (OFDM), BPSK, QPSK, CCK and QAM baseband modulation
technologies.
A high level of integration and full implementation of the power
management functions specified in the IEEE 802.11 standard minimize
system power requirements by using YL1023.
YL1023 module adopts QCA1023 single chip solution. The module design
is based on the QCA1023 solution.
