PCB Design review. How did I do?
Great design, make sure you use impedance control at the points that is required, and also make sure your traces are are well calculated for current capacity and etc.
Is this a two layers design

Debugging Intermittent CAN Bus Communication Failures on AVR128DA48
You can use an oscilloscope to monitor CAN_H and CAN_L signals for distortion, ringing, or voltage drops. Sometimes also if your power network is not properly grounded, you can receive some garbage message on the system.

Issues with Viewing PRINTF Output on STM32 Nucleo L476RG with X-Nucleo IDB05A1
Use a serial terminal tool (e.g., PuTTY, Tera Term, or HTerm) to connect to the virtual COM port.
Set baud rate to match your project's UART configuration.
In your code, redirect printf to UART

Troubleshooting CANBUS Flashing on Nucleo-F446 Board Using STM32 Bootloader
Most times you need to verify the voltages required for setup, i use one CAN transciever and i discovered it had two voltage rails. So confirm this

Troubleshooting CANBUS Flashing on Nucleo-F446 Board Using STM32 Bootloader
Check the CAN2 pin configuration on your Nucleo-F446 board. Ensure PB5 (CAN2_TX) and PB13 (CAN2_RX) are correctly connected to the external transceiver (MCP2551/SN65HVD230). Verify the transceiver's VCC and GND connections.
Also, confirm the bootloader mode is properly activated by monitoring the STM32's BOOT0 pin and reset sequence.
Are you using a CAN bus analyzer or sniffer to verify the CAN message is being transmitted correctly and not corrupted?

Ensuring Reliable Cloud Integration with ESP32 for Continuous Sensor Monitoring
Noisy power supply to ESP32's Wi-Fi module can cause disconnections. Faulty or loose connections, such as antenna or power cables, can also interrupt cloud connectivity.

NodeMCU and WLED Issues with Powering via Mains Adapter
Make sure the 5v supply is stable enough not to fluctuate, which is bad to the MCU.
Also ensure the LED is not consuming too much current, this can cause the MCU to trip off and enter a reset state

Logic for Sensor Measuring Natural Water Rise and Surface Pressure in a Well Setup?
The sensor measures the pressure of the water above it. The higher the pressure, the higher the water level. The sensor calculates the height of the water level based on this pressure.
Pressure = Water Height
The sensor uses this equation to determine how much pressure is driving the water to the surface, and thus calculates the natural rise of water above the sensor level.
