RC-TXFSK-433.42

RF Transmitter Overview

The RC-TXFSK-433.42 is a 433.92MHz FSK radio transmitter module designed for IoT and wireless data transmission applications. Operating on a standard pinout, the device functions within a DC voltage range of 2.4 to 3.6 volts. It delivers a transmit power of 10dBm with a typical current consumption of 14.5mA at the specified frequency. The module supports reliable short-range communication suitable for embedded systems requiring stable RF output in industrial or consumer environments.

RF Transmitter Feature Summary

• Supports Frequency Shift Keying (FSK) modulation for improved signal integrity
• Operates on low voltage DC supply ranging from 2.4V to 3.6V
• Features standard pinout configuration for easy integration

RF Transmitter Applications

• IoT sensor node transmission
• Wireless remote control systems
• Industrial telemetry data links

RF Transmitter Procurement Notes

Verify the specific operating frequency variant required, as the model designation indicates 433.42MHz while associated documentation references 433.92MHz. Confirm voltage tolerance matches the 2.4–3.6V input specification. Ensure the receiving end supports FSK demodulation to maintain link reliability. Check pinout compatibility with the target PCB layout before integration.

RF Transmitter Selection Notes

Select this module when FSK modulation is preferred over ASK/OOK for better noise immunity in crowded RF environments. The low current draw of 14.5mA makes it suitable for battery-powered devices. Ensure the application environment does not exceed the maximum DC voltage limit of 3.6V to prevent component damage.

RF Transmitter Part Context

This component belongs to the RadioControlli series of wireless modules, which includes various FSK and LoRa variants. These modules are engineered for embedded applications requiring standardized interfaces and consistent RF performance across different frequency bands within the ISM spectrum.

RF Transmitter Replacement Considerations

The RC-TFSK3-434 and RC-TFSK4-434 are documented alternatives offering identical electrical specifications including 10dBm power and 14.5mA current. Differences lie primarily in physical dimensions, with the TFSK3 measuring 20.32 x 11.43mm and the TFSK4 measuring 30.5 x 10.3mm.
