Overview

1.1

Introduction

The

E22-400M30S

is

based

on

the

SX1268,

a

new

generation

of

LoRa™

RF

chip

manufactured

by

Semtech,

USA.

It is

an

ultra-small

and

self-developed

433MHz,

470MHz

SMD

LoRa™

wireless

module.

Because

it

adopted

the

original

SX1268

as

main

core,

the

PA

and

LNA

is

built-in

also

based

on

the

previous

one,

which

makes

the

maximum

transmission

power

to

IW,

at

the

same

time,

the

receive

sensitivity

is

also

further

improved.

The

The

anti-interference

performance

and

communication

distance

have

been

further

improved

compared

to

the

previous

generation

LoRa™

transceiver,

and

far

superior

to

the

current

FSK

and

GFSK

modulation

products.

This

products obtained

FCC, CE

and

RoHS

certification

already

so

users

do

not

need

to

worry

about

the

performance.

Adopted

product

can

cover

an

ultra-wide

frequency

range

of

410~493MHz

and

is

backward

compatible

with

SX1278

and

SX1276.

Since

the

module

is

a

RF

transceiver

module

only,

users

need

to

use

the

MCU

or

use

a

dedicated

margin,

and

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

traces,

high-frequency

analog

traces,

and

power

traces

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(All

copper-covered

and

well

grounded),

and

must

be

close

to

the

digital

part

of

the

module

and

routed

in

the

Bottom

Layer.

Assuming

the

module

is

soldered

or

placed

in

the

Top

Layer,

it

is

also

wrong

to

randomly

route

the

Bottom

Layer

or

other

layers,

which

will

affect

the

module's

spurs

and

receiving

sensitivity

to

varying

degrees.

Assume

that

there

are

traces

with

large

electromagnetic

interference

around

the

module

(high-frequency

digital,

high-frequency

analog,

power

trace),

which

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

and

also

have

a

2.4GHz

TTL

protocol,

for

example:

The

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

of

the

case.

The

antenna

must

not

be

installed

inside

the

metal

case,

which

will

greatly

reduce

the

transmission

distance.

Itis

recommended

to

add

a

200R

protection

resistor

to

the

RXD/TXD

of

the

external

MCU.

SX1268/SX1262+PA+LNA.

Its

driving

mode

is

exactly

the

same

as

SX1268/SX1262.

Users

can

operate

according

to

SX1268/SX1262

chip

datasheet.

DIO1

and

DIO2

are

general-purpose

IO

ports,

which

can

be

configured

into

multiple

functions.

DIO2

can

be

connected

to

TXEN

and

not

connected

to

the

MCU's

10

port.

It

can

be

used

to

control

the

RF

switch

transmission.

If

not

used,

you

can

hang

it.

For

FAQ

The

communication

distance

will

be

affected

when

rate

will

be

affected

by

temperature,

and

co-channel

interference.

The

ground

will

absorb

and

wireless

radio

wave,

so

the

performance

will

be

poor

when

testing

Sea

water

has

great

ability

in

absorbing

wireless

radio

wave,

so

performance

will

be

The

when

the

incorrectly,

air

(the

higher

the

air

the

shorter

the

distance).

When

the

power

supply

at

room

temperature

is

lower

than

the

recommended

voltage,

the

lower

the

is,

the
