RF Solutions Tiny AM Transmitter Module, 433MHz

The RF Solutions Tiny AM Transmitter Module is a compact, hybrid RF transmitter operating at a stable 433MHz frequency. It provides a complete and ready-to-use solution for integrating wireless data transmission into your electronic projects, capable of sending data at speeds of up to 3KHz from any standard CMOS or TTL source.

This module is designed for reliability and ease of use, featuring a SAW (Surface Acoustic Wave) resonator that ensures a stable operating frequency without the need for any adjustable components. Its wide operating voltage range of 3 to 12 volts makes it highly versatile, suitable for use with various battery configurations and low-power systems.

The transmitter utilises ASK (Amplitude Shift Keying) modulation, an efficient and common method for sending digital data over radio waves. With a practical transmit range of up to 50 metres under optimal conditions, it is ideal for short-range remote control, data telemetry, security systems, and wireless sensor networks.
