The Great Search – 0402 Size RF Capacitor Kit for Antenna Tuning
from Adafruit Industries · host Adafruit Industries
We've been working on making for QT Py's for various chipsets and we were getting some connection issues on our S3 QT Py. Thanks to unexpected maker, we got a Hot Tip on how they had the same issue but fixed it with some pi network tuning! Tuning for an antenna can take swapping out a range of capacitors to get the best performance. The best way to do that is to get a RF capacitor kit, so you can try lots of different values quickly! Let's find a kit for 0402 sized capacitors that range from about 1 to 10pF and are C0G/NPO precision.
