Description

Long-distance wireless transmission (up to 500m in open area, 10kbps air data rate). Operating frequency range: 433-458.5MHz, supports up to 255 communication channels. Maximum transmit power: 100mW (20dBm), with 10 adjustable power levels. Built-in MCU enables serial communication with external devices; transmits up to 31 bytes per packet. Supports one-to-one and one-to-many transparent transmission via ID settings. Serial port baud rate adjustment automatically synchronizes with wireless transmission rate (10kbps–100kbps). Features a three-minute startup window for AT command mode: during this period, sending 'AT+ENABLE=1' enables AT mode for parameter configuration. After this period, the module operates only in data transmission mode and AT commands are treated as standard data.
