Product Description

1.Introduction
 

3161A-SL 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 upto 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 integrates a high-performance 32-bit microprocessor, a hardware security engine, and various

peripheral interfaces, 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. Its built-in SRAM and

flash can operate independently and even programming is allowed on the flash.
