currently，according the official of renesas information， RTD120D is obsolete，；
but I want some files about RTD120D, for example , Detector Board SCH in the RTD120D-EVK
thank you
Hello,
Thanks for reaching out Renesas Engineering Community.
Please let me inform you that the specific product is obsolete, which means that it's production has stopped and we do not recommend it for new designs.
For CO2 detection we recommend for new designs ZMOD4410 sensor from our MOX sensors.
Here you can have a quick overview of the product if you would like to:

Now regarding this sensor as already mentioned since it is obsolete the support you will receive in the future about this will be limited.
Now back to your question, you can find documents as the datasheet of the specific sensor in the link provided below:

Now regarding finding more information about the EVK please check this webpage:
https://www.renesas.com/en/products/sensor-products/environmental-sensors/thermopile-gas-sensor-detectors/rtd120d-evk-rtd120d-thermopile-gas-detector-co2-evaluation-kit
Regarding finding the schematics of the EVK if you will go through the manual of the EVK you will find the schematics:
