    kicad - change via pad to IC's pin pad

    i tried that way too.. pad size is changing but in 3d view i could see mask over pad and very small pad which can be soldered. In above picture as you can see the via property i was talking..

    kicad - change via pad to IC's pin pad

    yes @Brian, this is what i want. i wrote pad 1 in wrong place in hurry. i want to make via same as test point or IC pin pad. I am preparing single side pcb board. So, for that i will be use jumper on other side. i want to solder wire on this via. i tried to change the via size but i didn't get...

    What can be behavior for 3.3v PIC and 5v display

    Re: what can be behavior for 3.3v PIC and 5v display No. I was talking about uart only by saying TX and RX. i have connected other sensor(MLX temp sensor) on i2c which also works on 3v3. Sensor is working fine for me.

    What can be behavior for 3.3v PIC and 5v display

    Re: what can be behavior for 3.3v PIC and 5v display Thanks. I will try using pull up's first. But is this stuck behavior is expected after connecting 5v peripheral to mcu works 3v3?

    What can be behavior for 3.3v PIC and 5v display

    Re: what can be behavior for 3.3v PIC and 5v display yes i have connected other sensor there which works on 3v3. In both way i will have to use voltage translator.

    What can be behavior for 3.3v PIC and 5v display

    Hi, I am using one display works on 5 volt and interface is UART. And PIC16F886 runs on 3.3volt. what is the behavior if we interface both on uart. When i connect display to the controller and controller stops working. do i need to use voltage translator for 3.3V and 5V.
