🛠️ Model Specific Charging Flex Compatibility
- Tecno Spark 40 4G (Model: KM5): Ensure you get the specific Tecno Spark 40 4G KM5 USB Charging Board Flex Cable, which features integrated IC circuits supporting the full 45W SuperCharge fast charging capability.
- Tecno Spark 40 Pro (Model: KM6): Uses a distinct shape configuration. You can purchase the correct variant directly via Sahii Electronics India or look up the Tecno Spark 40 Pro KM6 USB Charging Dock on global supplier networks.
- Tecno Spark 40 Pro Plus (Model: KM7): This premium model requires a unique layout accommodating fast docking pins and secondary microphones. You can source it through specialized mobile part platforms like the Tecno Spark 40 Pro Plus KM7 USB Board listings.
- Tecno Spark 40C (Model: KM4K): A lower-tier configuration sub-board. A dedicated Tecno Spark 40C Charging Connector Board is required for drop-in installations.
🔍 Key Features of the Replacement Board
- Integrated Components: The assembly contains the primary Type-C USB data/power port, the voice microphone module, and terminal links for your phone’s cell network antenna wire.
- With IC vs. Without IC: When purchasing, it is highly recommended to buy the version labeled “With IC Chip”. Cheaper clones without the IC chip lack overload circuit protections and can severely bottleneck charging speeds or cause intermittent PC data connections.
- No Soldering Required: This sub-board acts as a plug-and-play assembly, allowing professional technicians or skilled DIYers to replace it easily via flex ribbon ribbons once the phone’s back housing is disassembled.
