Hello :)
I would be grateful for advices and recommendations about my layouts (they are public in my profile).
Are they good enough for doing the order?
Thanks.
PCB 1 (temperature sensor)
PCB 2 (relay for low-power load, 220V, less then 1A current)
Both devices get power from USB and have voltage regulator 5V -> 3.3V for the ESP32 WROOM module
A couple of minor points:
Sensor PCB1:
Move the ground track to the left to go up on the heat spoke so the track it is not over the gap:
Relay PCB2:
What current and voltage is the relay switching?
Are the tracks wide enough to carry the current?
Are the tracks far enough apart to give the required clearance for the terminal voltages?
In general:
See the check lists in (4) and (6) in (2) in:

Sensor PCB1:
thanks, Ive moved it.
Relay PCB2:
1. It calculated for low-power load (220v, less then 1A)
2. Tracks are wide enough for 1A
3. Clearance is also checked. Its good enough either.
I've got all needed answers from you. Thank you for you help and sorry for so many falts. I'll be more attentive next time.
@ykshtein,
No problem. I have reviewed smaller PCBs that have had far more faults that yours.
