Product Description
NF-05 & NF-05-S 2.4G wireless modules are independently developed by Ai-Thinker, they are with small size, low power consumption, high reliability, built-in PCB antenna.
The core processor chip Ci24R1 of the module is a high-performance 2.4GHz GFSK wireless transceiver chip, which is designed for various applications such as wireless audio and wireless data transmission: wireless mouse, key disk, wireless operation control, somatosensory equipment, smart grid, smart home.
NF-05 & NF-05-S modules have industry-leading low power consumption and RF performance, support GFSK/FSK protocol.
The chip integrates high PSRR LDO and smart ARQ base with protocol engine, the fast startup time of the chip is less than 160μS, and it is turned off ultra-low power consumption, which can reach 2μA and can meet various application scenarios power consumption requirements.
Need for a few external components, greatly reduces the system’s application cost.
Range was tested with 250Kbps speed and the communication range was found to be around ~200 meters.
Modules Compatibility
Comparison of different Modules
If you are looking for a lower power consumption, NF-03 & NF-01-S are recommended.
However, if you want to be compatible with BLE4.2 PHY & MAC (do not support connect, but support broadcasting and RX), then you can use the NF-05 & NF-05-S.
Application
This low power 2.4Ghz module can be used wireless remote, mouse, keyboard, Smart Home communication, Toys, etc.
