FRDM-KW019032 Compatibility with FXTH870

[swils226]

Hello,

I need a receiver for an FXTH870 development board that I am building. Is the FRDM-KW019032 compatible with the FXTH87 operating at 434 MHz?

What is the best guide to follow in order to program both the FXTH870 and the receiver so that they will communicate with one another?

Thank you

Hello S Wilson,

The FRDM-KW019032 is designed for 915 MHz and 868 MHz frequency bands. However, it can also work for 434MHz but the RF performance will not be optimal. For proper RF performance, I recommend modifying the board according to the BOM tables designed for 400MHz operation in the corresponding board’s manual:

Section 4.3.1 Bill of materials in FRDM-KW019032Freescale Freedom Development Board User's Guide

About the software side in the KW01, I recommend following the application note:

Using the Kinetis KW01 as the Receiver for the FXTH870xD TPMS Sensor – AN5136

Let me know any questions you may have.

Regards,

Gerardo
