MWA04 User Manual
The MWA04 module uses the Realtek RTL8710 chip solution and supports
IEEE 802.11b/g/n (2.4G frequency band 1T1R 150M). The module has a
total of 16 pins (/pads), which can provide up to 13 GPIO ports,
some of which can be reused with other interfaces, such as
supporting up to 7 PWM interfaces, 3 serial ports, and 1 I2C.
The module adopts 3.3VDC external power supply input, and the
external power supply needs to support a maximum current supply of
300mA. It is recommended to use a switching power supply solution
above 1MHz to provide better dynamic response. When determining the
power supply scheme, please pay attention to test that there should
be no obvious drop or jitter at the initial stage of power-on of 3.
3VDC, otherwise the module will be unsuccessfully reset and cannot
start normally.
The main application occasions of the module are smart home related
equipment, such as smart sockets, wall switches, light bulbs, etc.
The physical picture of the module is as follows:
