Problems using PTH components instead of SMD?

RafaelJureg · ‎2025-05-05

I am making a stm32f411ce board and I want make sure everything works because it's very expensive to order a pcb in my country. I want to use components like Hc-49 8mhz crystal(and dt-38 32.768khz) oscillators with ceramic PTH capacitors, the only smd parts will be the MCU and micro usb and maybe an ams1117 regulator, will I have some issue? is there anything different I have to do?

Hello,

Sorry the question is not clear. Do you need to use SMD crystals or not?

Do you have datasheets of these crystals?

Hello,

I don't see why it wouldn't work, STM32F401 discovery board was made with HC-49 for the 8MHz.

For the pth ceramic capacitors, as long as you put the right value, it should be fine too.
