The PCB trace antenna on the ESP32-C6 is often limited in range due to its design, which may not provide optimal radiation patterns compared to external antennas. A 50 cm range is pretty low for Wi-Fi or Zigbee, especially in environments where more distance is required.
If the power supply is unstable or provides incorrect voltages, it can cause malfunctions across different components. Use a multimeter to check the output voltages against the service manual (if available).
A welded core can help ensure that the magnetic flux generated by the transformer’s primary coil is contained effectively within the core material. The structure of the core influences the efficiency of the transformer, and welds help maintain its integrity and performance.
The bus bar method is the most robust solution and should work well with no weak spots. The 40cm wire after the resistor shouldn't be a major issue at 9600bps, but you could test the system to confirm. If the setup grows, this method offers the flexibility to add additional devices without much...
This is a DC submersible motor. I used it couple of times years ago and it had been unused since then. I need to use it again for a sprinkler project. When I took it out of my almirah today, I discovered this long crack on the motor's body. Do you think it is safe to use this motor anymore?
The key disadvantages themes for SiC MOSFETs you listed are ESD, threshold drift, short-circuit limits, internal gate resistance, and negative gate drive complexity. These are all technically valid and well-documented concerns in the industry.
