5 months ago It seems that the Unkown IC is an WSEN-PADS Absolute Pressure Sensor.

I'll try to verify that with my custom meteomodem m20 firmware by trying to communicate with in the next monthes.
Man you did an incredible work on your M20 reverse engineering ! Your pdf is a gold mine. 👌
I just got my 1st radiosonde some days ago and started working on it. I updated the portapack/hackrf mayhem firmware to allow everyone to decode GPS coordinates from M20 frames in the air using this pocket sdr. I plan to work on an alternative firmware to run on the onboard STM32 but I actually have only one M20 and wait for more qty to begin flashing new firmware on it. (don't wanna brick it) So I didn't test your firmware yet but I'm sure it can be a good inspiration for anyone who wants to make a new firmware for this devboards falling from the sky !
THANK YOU 🙏
