4 Recommended circuit diagram

5 Hardware design

It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible and the

module needs to be reliably grounded;

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 between the recommended supply voltage, if exceeding the maximum, the

module will be permanently damaged;

Please check the stability of the power supply. Voltage can not fluctuate greatly and frequently;

When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the

margin, so the whole machine is beneficial for long-term stable operation;

The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other

parts with large electromagnetic interference;

Bottom Layer High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under

the module. If it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and

Chengdu Ebyte Electronic Technology Co.,Ltd E30-900M20S User Manual

the copper is spread on the Top Layer of the module contact part(well grounded), it must be close to the digital part

of the module and routed in the Bottom Layer;

Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer or

other layers, which will affect the module's spurs and receiving sensitivity to varying degrees;

It is assumed that there are devices with large electromagnetic interference around the module that will greatly affect

the performance. It is recommended to keep them away from the module according to the strength of the

interference. If necessary, appropriate isolation and shielding can be done;

Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog,

power traces) around the module that will greatly affect the performance of the module. It is recommended to stay

away from the module according to the strength of the interference.If necessary, appropriate isolation and shielding

can be done;

If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is

still a risk of damage);

Try to stay away from some physical layers such as TTL protocol at 400MHz;

The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure that

the antenna is exposed, preferably vertically upward.

When the module is mounted inside the case, use a good antenna extension cable to extend the antenna to the outside;

When the antenna is installed inside a metal case, it will cause the transmission distance to be greatly weakened.

6 FAQ

6.1 Communication range is too short

The communication distance will be affected when obstacle exists;

Data lose rate will be affected by temperature, humidity and co-channel interference;

The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground;

Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea;

The signal will be seriously affected when the antenna is near metal object or put in a metal case;

Power register was set incorrectly or air data rate is set as too high (the higher the air data rate, the shorter the distance);

The power supply low voltage under room temperature is lower than our recommendation, the lower the voltage, the

lower the transmitting power;

Due to antenna quality or poor matching between antenna and module.

6.2Module is easy to damage

Please check the power supply source, ensure it is 1.8V~3.6V, voltage higher than 3.6V will damage the module;

Please check the stability of power source, the voltage cannot fluctuate too much;

Please make sure anti-static operation when installing and using, high frequency devices have electrostatic

susceptibility;

Please ensure the humidity is within limited range, some parts are sensitive to humidity;

Please avoid using modules under too high or too low temperature.

Chengdu Ebyte Electronic Technology Co.,Ltd E30-900M20S User Manual

6.3 BER(Bit Error Rate) is high

There are co-channel signal interference nearby, please be away from interference sources or modify

frequency and channel to avoid interference;

Poor power supply may cause messy code. Make sure that the power supply is reliable;

The extension line and feeder quality are poor or too long, so the bit error rate is high.

7 Production guidance

This product is a SMD module. When soldering the module, the soldering personnel must work in accordance with

the anti-static operation specification;

This product is an electrostatic sensitive product. If the module is not welded according to the specification, the

module may be permanently damaged.
