                  This module uses the domestic RF bonding chip BK2425, which integrates all the high-speed signal processing parts related to the RF protocol. Since the link layer is fully integrated on the module, it is very easy to develop. Automatic detection and automatic retransmission of lost data packets, retransmission time and number of retransmissions can be controlled by software, automatically storing data packets that have not received the response signal; after receiving valid data, the module automatically sends a response signal without additional programming; 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, six channel receiving channel addresses can be set at the same time, and the receiving channel can be selectively opened. . The SPI interface of the BK2425 can be connected by the hardware SPI port of the MCU or simulated by the I/O port of the MCU. The internal FIFO can interface with various high and low speed microprocessors, which is convenient for using low-cost MCU.

                  • Onboard 2.4G PCB antenna, ISM band, 2.54mm pin DIP8 package, compact size, easy to use for embedded applications.
                  • Supports six channels of data reception (one pair of six)
                  • Support GFSK modulation
                  • Supports 2Mbps/1Mbps/250Kbps data rate, and can set different transmit power
                  • Multi-frequency point: meet the needs of multi-point communication and frequency hopping communication, 2400MHz~2527MHz, 1MHz frequency hopping stepping
                  • Internally integrated high PSRR LDO
                  • Wide supply voltage range: 1.9~3.6V, typical 3.3V
                  • Average emission current as low as 18mA (4dBm)
                  • Receive sensitivity: -96dBm@250kbps
                  • Transmit power : 4dBm
                  • Four-wire SPI interface with speed up to 8MHz
                  • Internal packet processing engine
                  • Transceiver data hardware interrupt output
                  • Operating temperature: -20 ° C ~ 85 ° C
                  • The best transmission distance: less than 120 meters (250kbp open environment without shielding without electromagnetic interference) The reliable distance is recommended to be used within 30%-50%.
