A: Technically yes, but do not do this . Batteries require a CC/CV charging algorithm. Bypassing the charging circuit can cause the battery to overheat, swell, or explode. Always solder to the test points (TP701/TP702) which are after the protection IC but before the battery management.
| Model Number | USB Type | Pinout Variation | Charging Voltage | | :--- | :--- | :--- | :--- | | Nokia 105 (RM-908) | Micro-USB | Standard (No ID resistor) | 5V DC | | Nokia 105 (RM-1120) | Micro-USB | Requires D+/D- short for >500mA | 5V DC | | Nokia 105 (TA-1010) | Micro-USB | Proprietary resistor divider on ID | 5V - 5.5V | Nokia 105 Rm 908 Usb Pinout
Whether you are a mobile repair technician dealing with a broken port, or an enthusiast wanting to build a custom charging cable, understanding the and the alternative test points (TP701-TP704) is 90% of the battle. A: Technically yes, but do not do this
A: The internal charger IC on the RM-908 is limited to 450-550 mA. Using a 2A charger will not damage the phone; the phone will only draw what it needs. Always solder to the test points (TP701/TP702) which
on the sticker under the battery. Using the wrong pinout can cause overcurrent or failure to detect the battery. Part 7: Frequently Asked Questions Q1: Can I charge a Nokia 105 RM-908 with just two wires (red and black from USB)? A: Yes, absolutely. The phone does not require data negotiation to begin charging. Simply connect +5V to VBUS and GND to GND.
A: The CA-189 is a charging-only cable (no data lines). It has a standard micro-USB pinout (only pins 1 and 5 connected). It will work perfectly for charging the RM-908. Conclusion The Nokia 105 RM-908 USB pinout is simple, standard, and forgiving. While the micro-USB port might fail mechanically, the underlying PCB test points provide a robust solution for extending the phone’s life.
