PRODUCT FEATURES

The product advantages:

 ultra low power consumption: only 3.5mA;

 ultra high sensitivity: the typical value is 10dBm

 ultra small size: the area is only 10.5*10.5mm

Can be easily through the various certification?

 is the most important ultra low price

Main features

N high Q dielectric resonator frequency technology to replace the acoustic resonator, frequency stability up to plus or minus 150KHZ level

N super anti interference ability, built-in ripple suppression circuit, can work stably divided voltage power supply, the wave interference circuit in switching power supply, voltage regulator, which can save three terminal voltage regulator IC to reduce costs

N is stable and reliable, has a wide range of operating temperatures

N has a super small volume (10.5*10.5*2.6mm), module back no device, can cling to the circuit board mounting

N low radiation, through the international standard variety

The performance index

This module can be vertically arranged on the circuit board, namely the long groove to module is inserted in the groove welding, because the module back no devices can also be close to the back board flat installation

N should be installed to avoid placing the metal objects in the module over 5mm, otherwise it will affect the use effect

N soldering iron should be grounded

Operating frequency: 315MHz (C), 433.92MHz (D) (other frequency custom)

Working voltage: 5V (1.8-13V)

Working current: 3.5mA

Modulation mode: ASK/OOK

Sensitivity: typical 10dBm worst 8dBm

The maximum transmission rate: 4.8kbps

Receiving bandwidth: 1.8MHz (6dB)

The antenna impedance: 75 ohm

Data output: compatible with CMOS level standard

Dimensions: 10.5*10.5*2.6mm [L * w * thick]

Operating temperature: -40~+85 ℃ (-45~+100 ℃ custom)

Pin description

The 1.ANT antenna 2.GND ground 3.VCC power 4.DAT data output

N pinout order shown above are arranged from left to right, repeated pin only switched on only one

Matters needing attention

The N data output is compatible with the CMOS standard, data output to ground / power do not add a pullup / pulldown resistors and capacitors should be connected directly to the output data, and decoding the input, otherwise not only increase the cost and effect

The N signal is too strong when receiving module will be blocked, remote control distance above the recommended antenna module using 30cm.

The N antenna is very important for wireless transmission module, not connected with the antenna or antenna incorrect use can affect the result, wireless transmitting module usually use two kinds of antenna.

The first use of cord or wire as an antenna, 433.92MHz corresponds to 17CM long, 315MHz corresponds to 23CM long, using this antenna should pay attention to the antenna and away from the metal body, the antenna effect is good, low price, is the preferred species;

Second kinds of helical antenna, this antenna is small and easy to install, shown below standard helical antenna provides for us, this antenna properly tuned, the receiving frequency can be customized, antenna gain is more than -3dBi, note installation distance of over circuit board and the module of 5--10mm, otherwise it will affect the reception, the antenna effect than the first kind of, but the small volume.

Common problem.

The 1 module support multi-point communications?

Answer: can. But developers need to compile the software protocol, touch soon itself does not have any protocol function. Like the serial multi machine communication, the need for programming staff to develop communication protocols, the serial port to send and receive data in the module, but, despite receiving data receiving, transmitting module may send data, how the specific communication requires developers to deal with.

Note: please make more response and pulse transceiver data mode.

How far is the 2 communication distance?

Answer: empty ore place 200 meters is not the problem; a wall, through several layers of no problem!
