Adafruit QT Py ESP32-S3 - What Antenna Capacitors & Inductor?

Post by nightsd01 »

I can see on the publicly available schematic page for the QT Py ESP32-S3, it shows that the 2.4GHz SMD chip antenna with the standard 2 capacitors and an inductor. But I can't find what are the actual values for these components?

I am trying to build an extremely similar PCB design with the same exact chip, but I can't figure out what values to use for these components. I thought I could just use the same values I've used with success in previous ESP32-PICO-d4 projects, but it turns out, it's not that simple :)

Hey Mike! Were you able to check with the designer? This RF stuff has always been cryptic to me, it would be so helpful to know, thanks!

I haven't heard anything yet. I'll check again.
