    NodeMCU ESP-32S pitch

    Hello!

    I have several ESP-32S NodeMCU boards. I'm going to design a PCB board to connect to it by SIL header blocks. These boards have a pitch of 2,54mm? And the distance from side header pins is 25,4mm? This dimensions are standard for the reference of this board?

    I have tried to find a PCB footprint of the board but did not find any.

    Thanks,
    Bruno

    Re: NodeMCU ESP-32S pitch

    If you have these boards in hands, why not you measure them? By the way, at least with the ESP32 relative, the ESP8266, there are a number of NodeMCU's variants from many manufacturers, therefore in order to avoid mistake from someone which has another brand, I would suggest you share here a picture of the board that you got, if you do not have paquimeter or are not comfortable to scan coordinates of the pins with a ruler.

    Hi,

    There are datasheets... telling you the measures.

    ...but most ESP32 modules are 1.27mm pitch. Half of standard 0.1 inch spacing.
    If the module is on a board with USB interface and PSU, it is normally 2.54mm but width across sides varies form one manufacturer to another.

    Hello!

    Thanks for the inputs! I have attached the photos of the board. Today, I could measure it with a paquimeter and it has 23mm between the two pin headers and 2,54mm pitch:

    I have boards from different suppliers and I thought that it would be standard these two measures, but I'm afraid not since it varies between them.

    Thanks,
    Bruno
