HOPERF has developed the RFM310C, a Sub-1GHz wireless transceiver module designed specifically for the 868MHz band. Based on the CMT2310A Sub-1GHz wireless transceiver chip, the module is designed to simplify RF hardware development, debugging, and verification while maintaining low power consumption and wireless communication performance. The RFM310C supports multiple modulation schemes, including OOK, (G)FSK, and 4(G)FSK.
