esp32-WROOM-32E adapter board (power saving, breadboard friendly)

Overview

A breakout board for ESP32-WROOM-32(D/E) module that is:
+ Breadboard friendly
+ Break out all pins from ESP32-WROOM-32(D/E)
+ Low quiescent LDO regulator, support SOT-23/SOT-89/TO-92 footprints (recommend low quiescent current LDO such as MCP1700 and HT73xx and HT78xx)
+ Capacitors that stabilize LDO input and output
+ Detailed Pinout notations printed clearly on PCB, explaining functions of every pin, including ADC/DAC/Touch/UART/SPI/I2C/sensor/strapping pins.
+ Optional onboard LED that connects to GPIO2
+ Extra pins for Vcc and GND to easily power more sensors and actuators
+ 3x8 double sided "prototype board" area for easy extension (add more LEDs, MOSFET etc)

Detailed explanation of the flash encryption principle and steps of ESP32, ESP32S2, and ESP-C3 series
After the stm32 serial port is initialized, the microcontroller does not run automatically, most likely because printf is used
If you use the serial port to debug the program, but the serial port and the microcontroller are not working, Reset and Run are also checked, and the downloaded program is reset, power off and restart
Are the UART and IIC of the MSP430G2XX3 USCI independent?
I have come across the USCI of MSP430G2XX3, but my understanding of this peripheral is rather vague. Are the UART and IIC of this peripheral independent? What do UCSI A0 and UCSI B0 mean? Does the MSP
About btn7971 driver
I am a novice and I am working on this driver. I flashed the board and tested it myself, but it doesn't work. I attached the schematic diagram and asked the experts to point out the error.
Show off the M4 evaluation board I just got from TI
I have spent a day and read all kinds of English manuals, which made me feel dizzy. Fortunately, the environment is now set up and I can download new programs and run them.
