Nokia 105 Rm 908 Usb Pinout -

The Nokia 105 RM 908 uses a standard Micro-USB connector, which contains the following pins:

The copper test points on the Nokia 105 motherboard can easily lift off the board if subjected to excessive heat. Do not hold the soldering iron on the pad for more than 1 to 2 seconds.

: Solder jumper wires directly from a USB cable to the board.

Used for USB communication (limited support on RM-908).

After testing multiple RM-908 motherboards, the pinout is , but the ID pin is left floating. The critical aspect is the in-circuit test points on the PCB, which are easier to solder than the micro-USB port itself.

Once all connections are made, use a digital multimeter in continuity mode to ensure there are no shorts between adjacent pins (especially between VBUS and GND). Apply a drop of UV-curable solder mask or B-7000 glue over the jumper wires to prevent them from snapping due to vibration or subsequent plug insertions. Cure it with a UV light for 60 seconds.
