The BM2502-6x-2 is a Sub-1GHz low-IF FSK&OOK receiver module designed based on the BC2502C/D device, which has ultra-low power, high performance and low-cost. The module supports wireless applications in the 315MHz, 433MHz, 470MHz, 868MHz and 915MHz frequency bands and can be easily accessed using a 2-wire interface similar to the I2C interface. The symbol rate ranges from 0.5Ksps to 40Ksps, and the data rate ranges from 1Kbps to 50Kbps. When the frequency band is 433.92MHz, the receiving sensitivity can reach -108dBm if the modulation mode is FSK, and -110dBm if the modulation method is OOK.
