How to connect micro usb jack to pcb
I noticed the blutooth speaker charging port came out, so I purchased a replacement from Marker. Now I need to connect it to my PCB, but when trying, the 5 pins aren’t soldered properly. I suspect the lack of copper on that PCB might be the issue. Anyone have suggestions or ideas on how to fix this?
I can't send images directly. However, I can describe the old Micro USB port pins in detail if that helps. Let me know!
The pads on the PCB seem removed, but please share an image of the Micro USB connection for verification. To link another device, you need to trace the traces and connect further along that path. I’ve handled something similar with a USB Type C port—it was more complex but also more straightforward than this one. It required careful planning since USB Type C offers many connections, yet it provided four unlabeled attachment points. For context, Micro USB 2.0 includes power (ground and +5V), data lines (D+ and D-), a shield, and an extra unused pin. The ground connects to the shield, while D+ and D- are likely unused. The +5V goes to a capacitor and resistor. This appears to be primarily a charging port, not a data transfer interface. You could potentially rewire it using a makeshift wire between the +5V pin and the resistor/capacitor if needed. Make sure to research USB standards and consider using a multimeter for continuity checks. With some modification, this port might still be usable.
It's an amplifier board for a sound bar that works with just 5V and ground. The device uses a 5-pin USB micro connector, but one of the pins was damaged and removed from the board.
It's my Bluetooth sound bar PCB. The 5-pin micro USB port was removed recently. I attempted a fix but couldn't, suspect the pins may have been soldered off. My plan is to charge externally using a TP4056 lithium battery charging board. Is this feasible? Could it harm the board due to reverse voltage or other issues?
why connect 5v to the cap labeled c23? The positive side should face toward your first photo, negative toward the left. This setup is confirmed because c23 on the positive side links between the micropin’s positive terminal and the VCC pin of the LTC4054 next to it. It looks like you might have taken it off, but it’s fine—just add another one or skip it if needed.
