Chapter 4 Basic Operation
4.1 Hardware design
It is recommended to use a DC stabilized power supply to supply power to the module. The power supply ripple
factor should be as small as possible, and the module should be grounded reliably.；
Please pay attention to the correct connection of the positive and negative poles of the power supply. Reverse
connection may cause permanent damage to the module；
Please check the power supply to ensure that it is between the recommended supply voltages. If the maximum value
is exceeded, the module will be permanently damaged；
Please check the stability of the power supply, the voltage should not fluctuate greatly and frequently；
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% margin,
because the whole machine is conducive to long-term stable operation；
The module should be as far away as possible from the power supply, transformer, high-frequency wiring and other
parts with large electromagnetic interference；
High-frequency digital wiring, high-frequency analog wiring, and power wiring must avoid the bottom of the

module. If it is necessary to pass under the module, assuming that the module is soldered to the Top Layer, lay
copper on the top layer of the contact part of the module (all copper And well grounded), it must be close to the
digital part of the module and routed in the Bottom Layer；
Assuming that the module is soldered or placed on the Top Layer, it is also wrong to randomly route the wires on
the Bottom Layer or other layers, which will affect the stray and receiving sensitivity of the module to varying
degrees；
Assuming that there are devices with large electromagnetic interference around the module, it will greatly affect the
performance of the module. According to the intensity of the interference, it is recommended to stay away from the
module. If the situation permits, proper isolation and shielding can be done.；
Assuming that there are traces with large electromagnetic interference around the module (high-frequency digital,
high-frequency analog, power wiring), it will also greatly affect the performance of the module. According to the
intensity of the interference, it is recommended to stay away from the module. Isolation and shielding；
4.2 Software writing
The module chip solution is Winner Micro W600, and its driving method is completely equivalent to W600, and
users can operate according to the W600 chip book;
The GPIO15 and GPIO16 of the internal chip (external 2 and 3 pins) are general-purpose I/O ports, and the related
AT commands can be used for pins;

Chapter 6 Quick Start
The E103-W05 module is easy to use and easy to access the network, and is compatible with most E103-W01 AT
commands in this section. Therefore, when using our E103-W05, you can also use the E103-W01 host computer to
easily achieve For the parameter settings of E103-W05, users are guided to use the product through communication
examples between the module and the module, the module and the server, and the module and the client.
When the user configures the parameters of the module, first of all, the user needs to ensure that the working
voltage of the module is 3.0~3.6V (typical value is 3.3V), the serial port pins have been correctly connected to the
relevant serial port tools and can communicate normally.
