CM4 PCB Design
June 30, 2024, 19:35
Hello every one I am designing a very basic CM4 circuit. I need only one USB port for connecting camera or lte module. I am facing a problem to get the uart switch FSUSB42UMX its out of stock in my country and i dont have alot of time to finish my project so can i connect the USB_P and USB_N pins from the raspi CM4 (103 and 105 pins ) directly to USB A adding 5v and GND does that works any help plzzz.
actually i just found this in CM3 and the basic thing that come to me is to short circuiting the D+ D- with my port without using the FSUSB42UMX but iam not sure mabe i can leave for it a place after that seperately connect them by 0 ohm resistor is that safe or no
