Introduction:

NF-04 is a 2.4G wireless module with small size and on-board antenna. It has a high airspeed (up to 2Mbps), SPI interface, and a pure hardware module. It has high stability, high cost performance and good spectrum test characteristics. , small size, using all industrial grade components.

NF-04 can be widely used in various Internet of Things applications, and is suitable for wireless mouse and keyboard, wireless remote control, somatosensory equipment, active RFID, NFC, low-power self-organizing network wireless sensor network nodes. Ideal solution for IoT applications

Feature:

1. DIP-8 ultra small package, built-in 2.4G antenna, compact size, easy to use

2. Support data reception of six channels

3. Support normal modulation methods such as GFSK/FSK

4. Support 2Mbps/1Mbps/250Kbps data rate

5. Multi-frequency point: 126 frequency points to meet the needs of multi-point communication and frequency hopping communication

6. Internally integrated high PSRR LDO

7. Wide power supply voltage range: 1.9~3.6V

8. Average emission current as low as 110mA

9. Receive sensitivity: -96dBm@250kbps

10. Maximum transmit power: +7dBm

11. With four-wire SPI interface, the speed can up to 10MHz

12. Internal integrated intelligent ARQ baseband protocol engine

13. Transceiver data hardware interrupt output

14. Support 1bit RSSI output

15. Low application cost: BK2425 integrates all high-speed signal processing parts related to RF protocol, such as: automatic retransmission of lost data packets and automatic generation of response signals, etc. The BK2425 SPI interface can be connected with the hardware SPI port of the microcontroller or with a single-chip microcomputer. The I/O port is simulated, and the internal FIFO can interface with various high and low speed microprocessors, which is convenient for using low-cost single-chip microcomputers.

16. Easy to develop: Since the link layer is fully integrated on the module, it is very easy to develop. Automatic retransmission function, automatic detection and retransmission of lost data packets, retransmission time and number of retransmissions. Software control automatically stores the packet auto-answer function without receiving the response signal. After receiving valid data, the module automatically sends a response. Signal, no need to separately program carrier detection - fixed frequency detection built-in hardware CRC error detection and point-to-multipoint communication address control packet transmission error counter and carrier detection function can be used for frequency hopping setting can simultaneously set six receiving channel addresses, which can be selective The open receiving channel stamp hole has a 2.54mm pitch for easy embedded applications.
