Procurement Notes

Verify component authenticity through authorized distributors such as DigiKey or Tenet Technetronics. Confirm that the received unit matches the WPI469 designation and Pimoroni Ltd origin. Check datasheets for specific pinout and electrical characteristics before integration. Ensure compliance with local radio frequency regulations for 433.92 MHz operation. Review RoHS3 certification status if environmental compliance is required for the final assembly.

Selection Notes

Select the WPI469 when a simple, low-cost 433.92 MHz transmitter/receiver pair is needed for basic wireless connectivity. It is suitable for projects requiring non-data-intensive command signals rather than high-bandwidth streaming. Consider compatibility with common microcontroller GPIO pins and existing library support for the 433 MHz band. Evaluate range requirements against typical indoor/outdoor obstacles for this frequency.
