ESP32-S3-devkit

Overview

The ESP32-S3-32S module has 38 pins.

In addition to GPIO19 and GPIO20, these two pins are used to interconnect with USBD-/USBD+.

It should be noted that when using this development version to develop, do not use the two ports GPIO19 and GPIO20. Forcible use will cause the firmware to fail to be flashed through USB. You can only use the TTL method to flash in, which is very troublesome.

The components used are all widely used and cheap ones selected from Jialichuang's mall. The only unfriendly thing is that the resistors and capacitors are of 0603 specification, which is not friendly to rivals.

A question from 430TACLK
I saw on the datasheet that the TACLK pin is the clock source input pin of timer A, but what does it mean if it is directly set to high or low? I hope someone can explain it to me.
Issues with beacon level and superframe level in beacon mode in CC26xx TIMAC protocol stack
In the TIMAC protocol stack of CC2630, can the terminal node change its superframe order at any time by calling MAC_MlmeSetReq(MAC_SUPERFRAME_ORDER, &msa_SuperFrameOrder); while the beacon order remai
