Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

(esp32+adxl325+sdcard)Storing sensor data in sd card(in txt file) and then sending it to cloud.
I'd suggest sending data directly to AWS IoT Core (Free tier eligible) with the MQTT protocol. You can send data in JSON format. You could then use a serverless function to send that data to a DynamoDB (noSQL) database as the API is easy to use.

Raspberry Pi, ESP32, EMQ X and Node RED together
The basic functions of the esp32_mqtt_publish_subscribe.cpp program are:

Help Needed with Tauri Desktop App for NFC Card Enrollment on ESP32
For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory.

It's 2023 why embedded development is so cumbersome?(rant)
Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino.
- Is there an extension in vs code to do embedded programming
-
Debug program using PlatformIO and avr-stub
PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats.
-
Do you know some sbc or soc that can be programed to run rtos and c++ on top?
Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards.
-
Newbie question on identifying board in IDE
If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO)
-
Issue with Adafruit ESP32-S3: COM port switching, etc.
You might have better luck with PlatformIO than the Arduino IDE; it's better at automatically choosing the serial port, though I can't say I've used it under Windows.

Made some progress on the Chessboard this week
My other suggestion takes more work but will make your life oh so much better. Professionally I have used and highly recommend. https://platformio.org/ which is free!

Ask HN: Best books to learn embedded systems?
Will you be doing embedded Linux? Embedded RTOS? Bare metal? Microcontrollers? SoC (say, FPGA with a hard processor core)?
You can do a lot with QEMU. https://bootlin.com/ has a lot of great, free training material.
https://bootlin.com/doc/training/embedded-linux-qemu/embedde...
is one of my favorites.
Learning to cross-compile, do embedded debugging, the process of booting an embedded system (which varies depending on the answers to the above questions), learning how to read a technical reference for the processor you’re using as well as for peripherals you’re likely to interact with - SPI, i2c, UART, maybe PCIe, are all handy skills. Learn a bit about JTAG, hardware, reading schematics, etc. Even being able solder is helpful.
There may be books (I had a great embedded Linux book when I started) but there are lots of online materials too. Check out https://platformio.org/
There are fun embedded boards and projects for microcontrollers too - micropython on an rpi pico, tinygo, eLua, etc.
