Details Information

 Introduction 

3181A-S is a highly integrated 2.4 GHz Wi-Fi module that support the IEEE 802.11b/g/n baseband and RF circuit. It supports 20 MHz standard bandwidth and 5 MHz/10 MHz narrow bandwidth, and provides a physical layer rate up to 72.2 Mbit/s. Wi-Fi baseband supports the orthogonal frequency division multiplexing (OFDM) technology and is backward compatible with the direct sequence spread spectrum (DSSS) and complementary code keying (CCK) technologies, offering various data rates defined in the IEEE 802.11 b/g/n protocol. 

Module chipset including the SPI, UART, I2C, PWM, GPIO, and multi-channel ADC. In addition, it provides high-speed SDIO2.0 slave interfaces, with clock frequency up to 50 MHz.


 Features 

Operate at ISM frequency bands (2.4GHz). 

Maximum rate of 72.2 Mbit/s@HT20 MCS7. 

SDIO interface for Wi-Fi.
