1 Introduction

1.1 Brief Introduction

E220-400M30S is 1W module developed independently

based on new generation of LoRaTM RF chip LLCC68 from

Semtech. LLCC68 is suitable for 433MHz and 470MHz SMD

wireless module and uses industrial 32mhz crystal oscillator.

The original imported LLCC68 is used as the core of the

module, a power amplifier (PA) and a low noise amplifier

(LNA) are built on the original basis, so that the maximum

transmission power reaches 1W and the receiving sensitivity is

further improved. In the overall communication Compared

with products without power amplifier and low noise amplifier,

the stability is greatly improved. Compared with the previous

generation of LoRaTM transceivers, the anti-interference

performance and communication distance have been improved, further opening the gap with FSK and GFSK modulation

products. The product can cover an ultra-wide frequency range of 410~493MHz.

Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.

1.2 Application

Home security alarm and remote keyless entry;

Smart home and industrial sensors, etc;

Wireless alarm security system;

Building automation solutions;

Wireless industrial remote controller;

Health care products;

Advanced meter reading architecture (AMI);

Automotive industry applications.

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, such as reverse

connection may cause permanent damage to the module;

Please check the power supply to ensure that it is between the recommended supply voltage. If it exceeds the

maximum value, the module will be permanently damaged;

Please check the stability of the power supply. The voltage should not fluctuate greatly and frequently;

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

which is conducive to the long-term stable operation of the whole machine;

The module should be far away from the power supply, transformer, high frequency wiring and other parts with

large electromagnetic interference;

The high-frequency digital wiring, high-frequency analog wiring and power wiring must avoid the lower part of the

module. If it is necessary to pass through the lower part of the module, it is assumed that the module is welded on

the top layer, and the copper is laid on the top layer of the module contact part (all copper is laid and well grounded),

which must be close to the digital part of the module and laid on the bottom layer;

Chengdu Ebyte Electronic Technology Co.,Ltd. E220-400M30S User Manual

Assuming that the module is welded or placed in the top layer, it is also wrong to route at will in the bottom layer or

other layers, which will affect the spurious and receiving sensitivity of the module in different degrees;

Assuming that there are large electromagnetic interference devices around the module will greatly affect the

performance of the module, it is recommended to keep away from the module according to the intensity of

interference, and appropriate isolation and shielding can be done if the situation permits;

Assuming that there are lines (high-frequency digital, high-frequency analog and power lines) with large

electromagnetic interference around the module, the performance of the module will be greatly affected. According

to the intensity of interference, it is recommended to keep away from the module. If the situation permits,

appropriate isolation and shielding can be done;

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

still risk of damage);

The antenna installation structure has a great influence on the module performance, so it is necessary to ensure that

the antenna is exposed, preferably vertically upward. When the module is installed inside the housing, the

high-quality antenna extension line can be used to extend the antenna to the outside of the housing;

The antenna must not be installed inside the metal shell, which will greatly weaken the transmission distance.

4.2 Programming

This module is LLCC68+PA+LNA, and its driving method is completely equivalent to LLCC68, and users can

operate in accordance with the LLCC68 chipset datasheet;

DIO1, DIO2 and DIO3 are common IO ports, which can be configured into multiple functions. DIO2 can be

connected to TXEN, not to IO port of MCU, and is used to control RF switch emission. See LLCC68 manual for

details, and can be suspended if not used;

The internal use of 32mhz passive crystal oscillator, without pin control, software program control can be;

The differences between LLCC68 and SX1262 / SX1268 were as follows

1. SX1262 / SX1268 supports spread spectrum factors SF5, SF6, SF7, SF8, SF9, SF10, SF11 and SF12;

LLCC68 supports spread spectrum factors SF5, SF6, SF7, SF8, SF9, SF10 and SF11.

2. LLCC68 can set the spread spectrum factor and receive bandwidth:

LoRa® Rx/Tx, BW = 125 – 250 – 500 kHz

LoRa®，SF = 5 - 6 - 7 - 8 - 9 for BW = 125 kHz ，

LoRa®，SF = 5 - 6 - 7 - 8 - 9 - 10 for BW = 250 kHz ，

LoRa®，SF = 5 - 6 - 7 - 8 - 9 - 10 - 11 for BW = 500 kHz；

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

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.
