Re: ESP32-S3 Hardware Design Guidelines | 硬件设计指南
Hi Rudi,
Thanks for posting this!
On page 12, section 2.5 RF of the esp32-s3 hardware guidelines it doesn't specify the pin impedance for the esp32s3 QFN 7x7 56 pin package, compared to the esp32 guidelines (https://www.espressif.com/sites/default ... nes_en.pdf) which specify " output impedance of the RF pins of ESP32 (QFN 6*6) and ESP32 (QFN 5*5) are (30+j10) Ω and (35+j10) Ω,
respectively".
Is the impedance known for the s3, or could you recommend a pi circuit and CL filter to match with the s3 on standard FR4 2 layer 1oz copper?
Any comments or help would be greatly appreciated,
Liam
