RF Transmitter Procurement Notes

Verify the specific pinout configuration against your PCB design, as the module uses a standard SIP footprint. Confirm that the required operating voltage aligns with the 2.4V to 3.6V specification. Ensure an appropriate external antenna is sourced separately, as it is not included with the module. Check for any specific mounting requirements related to the 30.5 x 10.3mm form factor.

RF Transmitter Selection Notes

Select this module when a compact, low-power RF transmitter is needed for fixed-frequency applications. It is suitable for designs requiring FSK modulation at 433.92MHz. Consider the 10dBm output power for range requirements. Verify compatibility with microcontrollers providing the necessary logic levels and current supply within the specified voltage window.

RF Transmitter Part Context

This component belongs to the RC-TFSK series of radio transmitter modules from RadioControlli.
