433.92 MHz ASK RF Transmitter Unit with SYN115, 10 dBm Output, and PCB Antenna
The M5Stack U114 Unit RF433T is a compact 433.92 MHz wireless RF transmitter designed for short-range remote-control and data-transmission applications. It integrates the SYN115 RF transmitter IC and uses ASK modulation to transmit digital data at rates up to 10 kbps. With an RF output power of 10 dBm and an integrated PCB antenna, the module provides a specified stable transmission range of up to 10 m under suitable operating conditions.
The module connects to compatible M5Stack controllers through an HY2.0-4P Grove interface and uses a single RF_TX digital signal for transmission control. Its compact 48 × 24 mm enclosure makes it suitable for security systems, wireless control, building automation, automatic meter reading, and other embedded 433 MHz applications. For two-way system development, the transmitter can be paired with a compatible M5Stack RF433 receiver unit.
