1 OVERVIEW

1.1 Brief Introduction

E07-900M10S is an independently developed 410-450MHz SMD wireless

module based on the CC1101 chip produced by Texas Instruments (TI), using

industrial-grade high-precision 26MHz crystal oscillator.

Due to the adoption of the already mature CC1101 chip as the core of the

module, its stability has won unanimous praise from users, and there is no need to

worry about compatibility. This module is mainly aimed at smart home, industry,

scientific research and medical, and short-distance wireless communication

equipment. It can provide extensive hardware support for data packet processing,

data buffering, burst transmission, received signal strength indicator (RSSI), clear

channel assessment (CCA), link quality indicator, and wireless wake-up (WOR).

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

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 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 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

Chengdu Ebyte Electronic Technology Co.,Ltd E07-900M10S User Manual

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);

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 Programming

It can complete the wireless data transceiving by operating its control register and transceiving buffer. Please refer

to the latest CC1101 data sheet for the timing operation of module register.

GDO0 is a general purpose I/O port，see CC1101 user manual；

GDO2 is generally configured as an IRQ-like function, or not connected. SPI query mode can be used to obtain the

interrupt status, but it is still recommended to use external interrupt by connecting to a MCU;

After CC1101 restores IDLE mode or configured as sleep mode, it is recommended to reinitialize the power

configuration table.

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.

6.2 Module 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.

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;

The clock waveform on SPI is not standard, check whether there is interference on the SPI line, and the SPI bus line

should not be too long;

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.
