I've run into similar issues before, and in my case, the problem ended up being related to grounding and connector routing rather than the UART peripheral itself.
One thing I'd definitely consider is keeping the sensor, power, and communication wiring separated where possible. If the analog...
If you already see framing errors during BLDC switching ..... rerouting alone may help but is not a guaranteed fix.
If traces are short and you can keep them away from the switching node ..... rerouting & grounding improvements might be enough.
If they must stay anywhere near motor driver paths...
Yeah, definitely .... LED power traces should be much thicker than logic traces because they carry more current. For a few hundred mA per LED, 1 mm or wider is usually safe, while ESP32 logic/data traces can stay 0.2–0.3 mm.
Another tip: try to keep LED traces short and direct, and avoid...
It sounds like your ESP32 resets are probably due to current draw. Even with extra capacitors ..... can’t reliably supply multiple LEDs at once .... wires and contacts have too much resistance. You shouldpower the LEDs from a separate 5 V supply ... capable of handling all LEDs ..... keeping the...
Cause: One LED in series burning out breaks the circuit; could also stress the driver or resistors.
Fix: Replacing the burnt LED can restore the board if no other damage exists.
Replacement LED: Match forward voltage, current, color, package, and polarity.
Check: Inspect driver, resistors, and...
I hope somebody will come forward to provide you with design and installation services for the whole project. However, it is possible to implement such surveillance projects with a Raspberry PI and a Raspberry Pi camera. You can see an example here...
Go with a constant-voltage driver rated for 24V. It should have enough wattage to handle your setup.
Choose a driver with at least 20-30% overhead, so a 24V driver rated for 250W is ideal. Here is a constant current LED driver design that you may take a look at...
You can find crystal oscillators that provide fixed-frequency outputs, including 200 MHz models, or programmable oscillators that can be set to a specific frequency.
If you need a flexible testing setup, a bench-top signal generator can generate precise clock signals at virtually any frequency...
You mentioned that the driver is set to 4.2A, which seems quite high for a NEMA 17 motor rated at 1.5A. Overdriving the motor may cause excessive heat and potentially damage it over time. Set the driver current to match your motor’s rated current. For the NEMA 17 motor you linked, set it to...
You can use IRLZ44N or STP55NF06L.

You can also make a motor driver module by yourself like this...
I am sorry, but I can't see the pictures well due to the very slow internet connection. However, I can guide you to a good Altium tutorial here: https://www.pcbway.com/project/shareproject/Altium_Designer_Step_by_Step_Guide_on_PCB_Board_Design_890f88b1.html
From this, you can learn how to design...
Yeah. That will be good. I can see in your photo, there is a small PCB. If you want to design an advanced PCB by yourself for this project, you can see here: https://www.theengineeringprojects.com/2024/06/advanced-manufacturing-materials-for-pcb.html
