NiceRF is a technical company which engaged in researching, developing, producing and selling IOT(internet of things) products.
We devoted ourselves on providing good RF modules, walkie talkie modules and integrated digital sensor modules.
Meanwhile, ODM and OEM projects are welcomed.With more than 12 years experience of product design in RF and sensors, we have earned a good reputation among our customers.
Our company's RF4463PRO RF transmitter and receiver module uses Silicon Lab si4463, which is a highly integrated wireless ISM band transceiver chip.
It has extremely low receiving sensitivity (-126 dBm), coupled with the industry-leading output power of +20 dBm, ensures extended range and improved link performance.
RF4463PRO uses lead-free technology for production and testing strictly.
It also meets RoHS and Reach standards.
Dmr818&828s is a 2W long distance Digital walkie talkie module, it comes with built-in high performance microcontroller, digital mobile radio IC and RF power amplifier.
All parameters(CTCSS, CDCSS, SQ, Predefined channels etc.) can be easily modified with protocol. With external power supply, speaker, and audio amplifier, it is easy to become a professional digital walkie talkie.
Simplified interface and Ultra small size make this module widely used in various applications and conveniently embedded into various handheld device.Remark: there are two versions of this module: DMR818-NVOC & DMR818-AMBE. DMR818 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
SA316 series products are divided into transmitter module SA316-TX and receiver module SA316-RX.
This series of solutions adopts wireless high-quality voice transmission chip to design, it can support external PCM / IIS dual-mode digital audio interface, and the module is The customer provides a standardized serial interface.
The user can quickly and easily set the module's transceiver frequency, sound size, microphone gain and other parameters through the serial port command, which is widely used in occasions that require relatively high sound quality.
The wireless switch module SA809-RX consists of walkie talkie and DTMF decoder, it works with walkie talkie to succeed long range wireless control.
Any walkie talkie with DTMF function in the market can be used as transmitter. For example, the GP338 of Motorola. When SA809-RX receives the signal of transmitter, it will decode and compare with the password preset before.
The high current mosfet will be driven to output if the input signal are verified. SA809-RX is very high security with 1~10 digital password and 400~480MHz frequency channel.
