Hello. I assembled the PCB and I have a problem, I have soldered the parts to M1 and when I measure the voltage with a meter, while PWM is at 0, the voltage is 3.44v and when PWM is at 255 it is 3.27v. Does anyone have any idea what it could be or something? Is this the case with the connection or m...

I will also add that I added a capacitor to the CH340C, increased the track width to 0.62mm, the same as the vias, and added 3 vias on the power supply connection to the motor, as you wrote earlier.

Thanks for your advice, thinking about it, it seems very wise. Tomorrow evening I will check all connections to make sure they are correct and place an order for a PCB. If anyone has anything else to add, please write.

Thank you for your answer, it is very helpful. 1) The idea is that the USB will only be used to upload the code and the battery will be disconnected during this time, can it stay like this or should I change something? 2) I added resistors and capacitors to EN (R21 -> 3.3v, C15 -> GND) and GPIO0 (R2...

Hello, I would like to create a drone based on ESP32 with 4 DC motors and MPU6050. I added ch340c to be able to upload the code to esp and USB-C. Can anyone check if the pcb is designed correctly, what should I change or add, if the paths are correctly routed and connected to the correct pins? https...
