9 Hardware Design

It is recommended to use a DC regulated power supply to power the module, the power supply ripple coefficient should be as small as possible, and the module should be reliably grounded;
Please pay attention to the correct connection of the positive and negative terminals of the power supply, if reversed it may cause permanent damage to the module;
Please check the power supply to ensure that it is between the recommended supply voltages, if it exceeds the maximum value, it may cause permanent damage to the module;
Check the stability of the power supply to ensure that the voltage does not fluctuate significantly and frequently; When designing the power supply circuit for the module, it is often recommended to keep more than 30% of the
residual capacity, and have the whole machine is conducive to long-term stable operation; Module should be as far away as possible from the power supply, transformers, high-frequency alignments and
other electromagnetic interference in the larger part; High-frequency digital alignment, high-frequency analogue alignment, power supply alignment must be avoided
below the module, if really have no choice but to go through the module below, assuming that the module is welded in the Top Layer, the Top Layer in the contact part of the module to pave the ground copper (all paved with copper and a good ground), must be close to the module digital part and the alignment of the line in the Bottom Layer; Assuming that the module is soldered or placed in the Top Layer, it is also wrong to route the wires randomly in the Bottom Layer or other layers, which will affect the spuriousness of the module as well as the reception sensitivity in different degrees; Assuming that there is a large electromagnetic interference around the module device will also greatly affect the performance of the module, according to the intensity of the interference is recommended to stay away from the module, if the situation permits you can do appropriate isolation and shielding; Assuming that there is a large electromagnetic interference around the module alignment (high-frequency digital, high-frequency analogue, power supply alignment) will also greatly affect the performance of the module, according to the intensity of the interference is recommended to be appropriate away from the module, if the situation permits you can do appropriate isolation and shielding; Communication line if the use of 5V level, must be connected in series with 1k-5.1k resistor (not recommended, there is still a risk of damage); The antenna installation structure has a greater impact on the module performance, be sure to ensure that the antenna is exposed, preferably vertical upwards. When the module is installed inside the chassis, a good quality antenna extension cable can be used to extend the antenna to the outside of the chassis;

The antenna must not be installed inside the metal casing, which will result in a great weakening of the transmission distance.

10 Frequently Asked Questions

EWM226 Series Specification

10.1 Unsatisfactory transmission distance
When there are linear communication barriers, the communication distance will be attenuated accordingly; Temperature, humidity, and co-frequency interference, which will lead to higher communication packet loss rate; The ground absorbs and reflects radio waves, and the test effect is poorer near the ground; Seawater has a strong ability to absorb radio waves, so the test effect is poor near the sea; metal objects near the antenna, or placed in a metal shell, the signal attenuation will be very serious; Incorrect power register settings, over-the-air data rate settings are too high (the higher the over-the-air data rate, the
closer the distance); The low voltage of the power supply at room temperature is lower than the recommended value, the lower the
voltage, the lower the power generation; The antenna is poorly matched to the module or the quality of the antenna itself.
10.2 Modules are vulnerable
Please check the power supply to ensure that it is between the recommended supply voltages, exceeding the maximum value can cause permanent damage to the module;
Please check the stability of the power supply, the voltage can not be large and frequent fluctuations; Please ensure that the installation and use of the process of anti-static operation, high-frequency devices
electrostatic sensitivity; Please ensure that the installation and use of the process of humidity should not be too high, part of the components
for humidity-sensitive devices; If there is no special demand is not recommended in too high, too low temperature use.

10.3 BER is too high
There is interference from the same frequency signal nearby, stay away from the source of interference or modify the frequency and channel to avoid interference;
Unsatisfactory power supply may also cause garbled code, be sure to ensure the reliability of the power supply; Extension cables, feeder cables of poor quality or too long, can also cause high BER.

11 Welding instructions

EWM226 Series Specification

11.1 Reflow temperature

When reflow soldering, all temperatures are package centre temperatures, measured on the upward facing package surface (leads placed downwards, i.e. live bug orientation). If reflow soldering is not used to measure the temperature of the module in the direction of the live bug (leads are placed facing upwards, i.e. dead bug direction), the measured Tp temperature is within ± 2 ° C of the Tp temperature measured in the live bug direction, which still meets the requirements of Tc. Otherwise, the temperature profile should be adjusted to meet the requirements of Tc. For accurate measurement of the actual peak temperature of the package body, it is recommended to use the method recommended by JEP140 for oven temperature testing.
In order to obtain better soldering results, the production plant is recommended to be controlled at a constant temperature of 25.
When the soldered parts need to reset the temperature profile, a carrier fixture of the same construction should be used to pass the reflow soldering, or it has been verified to have an equivalent thermal load.
The reflow profiles in this document are intended as recommendations for soldering only EBYTE modules and should not be used to confirm the actual assembly profile of the user. The actual production process should be based on the specific production process, needs and board design to develop the actual production assembly profile, and should not exceed the parameters in the table below.
