RD-03E-G

RF Transceiver Modules And Modems Overview

The Ai-Thinker RD-03E-G is a 24GHz ISM band radar transceiver module designed for ranging and gesture detection applications. Operating within the 24GHz to 24.25GHz frequency range, it utilizes the S3KM111L chip to provide high-precision millimeter-wave sensing capabilities. The module supports a data rate of 256Kbps via a UART serial interface and requires a 5V supply voltage. It features an on-board patch antenna and is housed in a 5-DIP package suitable for through-hole mounting. The device operates reliably across a temperature range of -40°C to 85°C.

RF Transceiver Modules And Modems Procurement Notes

Verify the specific suffix 'G' against manufacturer documentation to confirm pinout compatibility and firmware version. Ensure the selected variant matches the required through-hole mounting style and DIP package dimensions for PCB layout alignment. Cross-reference the S3KM111L chip specifications with system power budget requirements.

RF Transceiver Modules And Modems Selection Notes

Select this module when through-hole assembly is preferred over surface mount alternatives like the RD-03D. Consider the 24GHz frequency band for short-range detection needs where lower frequencies lack precision. Evaluate the UART interface speed against microcontroller processing capabilities to ensure timely data handling for real-time gesture applications.

RF Transceiver Modules And Modems Part Context

The RD-03E-G belongs to Ai-Thinker's family of 24GHz millimeter-wave radar modules. It shares core sensing technology with variants such as the RD-03E-R and RD-03D but differs in packaging and mounting configuration. This specific model targets applications requiring robust through-hole integration while maintaining the high sensitivity of silicon-based mmWave radar solutions.

RF Transceiver Modules And Modems Replacement Considerations

The RD-03E-R serves as a direct alternative with identical functional specifications but utilizes a different package configuration. The RD-03D offers similar radar performance but employs a surface-mount 4-SMD package rather than through-hole DIP. Verify mechanical footprint compatibility before substituting these models.
