Brief introduction

E10-433MS1W is a 1W wireless module developed by Ebyte, working at 433MHz based on chip SI4463 from Silicon Labs. Based on originally imported RF IC SI4463 form Silicon Labs, E10 series are small size Sub-1GHz SMD wireless transceiver module, with SPI interface and 26M crystal oscillator, developed by Chengdu Ebyte. The 30dBm module with PA and LNA, the communication stability and distance are largely improved. Since the module is a pure RF transceiver module, you need to use the MCU driver or a dedicated SPI debug tool.

Feature

• The communication distance tested is up to 6km
• Maximum transmission power of 1W, software multi-level adjustable；
• Support the global license-free ISM 433MHz band；
• Support air date rate of 1.2kbps～1000kbps；
• Support multiple modulation methods, (G)FSK, 4(G)FSK, (G)MSK，OOK ；
• Support 64/128 byte Transceiver Data Register (FIFO);
• Support 2.5V~5.5V power supply, power supply over 5.0 V can guarantee the best performance；
• Industrial grade standard design, support -40 ~ 85 °C for working over a long time；

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. The 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 fluctuate 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 the 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.

Software editing

• GPIO0 \ GPIO1 \ GPIO2 \ GPIO3 are configurable I/O ports for various applications， see more in SI4463 datasheet.It can be floated when not used.
• 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

FAQ

The communication range is too short

• The communication distance will be affected when an obstacle exists.
• Data lose rate will be affected by temperature, humidity, and co-channel interference.
• The ground will absorb and reflect wireless radio waves, so the performance will be poor when testing near the ground.
• Seawater has a great ability in absorbing wireless radio waves, so performance will be poor when testing near the sea.
• The signal will be affected when the antenna is near a metal object or put in a metal case.
• The power register was set incorrectly, 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 2.5V, the lower the voltage, the lower the transmitting power.
• Due to antenna quality or poor matching between antenna and module.

The 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 the power source, the voltage cannot fluctuate too much.
• Please make sure antistatic measures are taken when installing and using, high-frequency devices have electrostatic susceptibility.
• Please ensure the humidity is within a limited range, some parts are sensitive to humidity.
• Please avoid using modules under too high or too low temperatures.

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;

Antenna recommendation

The antenna is an important role in the communication process. A good antenna can largely improve the communication system. Therefore, we recommend some antennas for wireless modules with excellent performance and reasonable price.
