3181M-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.
