1 Overview

1.1 Brief introduction

E10-433MD3 is small SMD wireless module working at

433MHz developed based on chip SI4438 from Silicon Labs.

Due to the use of the imported Si4463 as the core of the module,

its stability has been well received by users, and compatibility is not

a concern. The module is aimed at smart home, wireless meter

reading, scientific research and medical, and medium and long

distance wireless communication equipment. Since RF performance

and component selection are in accordance with industrial standards,

and the product has obtained FCC, CE, RoHs and other international

authoritative certification reports, users do not need to worry about

its performance. With its stable and reliable characteristics, it is favored by the majority of users. Compared with the old

products, it has made great progress in receiving current, receiving sensitivity, transmitting power, receiving rate range

and anti-interference ability. High precision 26MHz crystal is used.

Since the module is a pure RF transceiver module, you need to use the MCU driver or a dedicated SPI debug tool.

4. Basic operation

4.1 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 it is within the recommended voltage otherwise when it exceeds the

maximum value the module will be permanently damaged；

Please check the stability of the power supply, the voltage can not be fluctuated 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.；

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 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 2.4GHz , for example: USB3.0；

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；

The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly

weakened.

4.2 Software editing

GPIO0 \ GPIO1 \ GPIO2 \ GPIO3 are configurable I/O ports for various application ，see more in SI4438

datasheet.It can be floated when not used.

Chengdu Ebyte Electronic Technology Co., Ltd. E10-433MD3 User Manual

IRQ pin can also be disconnected. The SPI query mode can be used to obtain the interrupt status. However, it is

recommended to use the external interrupt of the MCU.

SPI communication rate should not be set too high, usually around 1Mbps.

Please refer to “Operating Modes and Timing” for SI4463 status switch，the switch between TX and RX should be

through Ready, can not be switched directly.

Re-initialize register configuration when the chip is idle for higher stability.

For controlling GPIO2 ,GPIO3 externally，pin status is as follows：

In tx mode：GPIO2 = 0; GPIO3 = 1;

In rx mode：GPIO2 = 1; GPIO3 = 0;

If the SI4463 is required to control itself, the mode of the configuration pins can be as follows when

the program is initialized:

SI44XX_GPIO_CONFIG( 0, 0, 32|0x40, 33|0x40, 0, 0, 0 );

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 affected when the antenna is near metal object or put in a metal case.

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

Chengdu Ebyte Electronic Technology Co., Ltd. E10-433MD3 User Manual

distance).

The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the

transmitting power.

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

6.2 Module is easy to damage

Please check the power supply source, ensure it is 2.0V~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 antistatic measure are taken 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.

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;
