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.See on Digi-Key here! https://www.digikey.com/short/5bttfhdmSee other episodes of The Desk of Ladyada in the playlist here https://www.youtube.com/playlist?list=PLjF7R1fz_OOXUtaFu7-_D1UCugC8OecKvand other Great Searches in the playlist here.https://www.youtube.com/playlist?list=PLjF7R1fz_OOVHqJN28IbXLBj1FKCxw-xDVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/
