Alps Tb8163p3-bsp _verified_ -
ALPS: The software development environment or manufacturer alias for generic MediaTek (MTK) Android devices.
TB8163: Points to the MediaTek MT8163 chipset. This is a 64-bit quad-core SoC commonly used in budget tablets (like older Amazon Fire HD or generic 7-10 inch models).
P3: Likely indicates a specific hardware revision or "Project 3" iteration of that motherboard.
BSP: Stands for Board Support Package. It is the layer of software that allows the Android operating system to communicate with the specific tablet hardware (camera, screen, Wi-Fi). 📸 Camera & Hardware Specs alps tb8163p3-bsp
According to device logs from databases like Camera FV-5, this specific hardware configuration typically features: Resolution: 2.1 Megapixels (1920×1080). Focus: Fixed focus (no autofocus). Sensor Size: Approximately 7.7 mm². ISO Range: 100–6400.
Stabilization: Electronic Image Stabilization (EIS) supported via software. 💻 Common Use Cases You will usually see this string in two scenarios:
System Information: It appears in the "About Tablet" section or benchmarking apps as the "Model" or "Build Number." ALPS : The software development environment or manufacturer
Firmware Repair: Techs look for this specific string to find the correct Scatter File (firmware) to fix a "brick" or software loop using tools like SP Flash Tool. ⚠️ Important Considerations
Software Updates: These devices rarely receive official over-the-air (OTA) updates. Most remain on the Android version they were shipped with (often Android 6.0 or 7.0).
Finding Firmware: If you are looking for the firmware file, ensure you match the Motherboard ID printed on the physical board inside the device, as "tb8163p3" can sometimes have slight variations in screen drivers. To help you further, could you let me know: Are you trying to fix a tablet that won't turn on? Do you need to download specific drivers or firmware? Symptom 1: The "Ghost Touch" or "Jittery Cursor"
Are you a developer looking for the source code for this BSP?
Symptom 1: The "Ghost Touch" or "Jittery Cursor"
- Cause: Defective ground isolation. The module’s capacitive sensing becomes overly sensitive due to a failing electrolytic capacitor on the DC input line.
- Fix: Requires reflowing the power management IC or replacing the module entirely (reprogramming required).
Pinout and electrical connections
- Pin arrangement (look at component with actuator toward you):
- Left pin — end terminal 1
- Middle pin — wiper (variable output)
- Right pin — end terminal 2
- For a simple voltage divider: connect end terminals across your fixed supply (e.g., 0–5 V) and take the wiper as the variable voltage output.
- For use as a variable resistor (rheostat): use one end terminal and the wiper; leave the other end unconnected.
Recommended usage tips
- Debounce/filter the wiper signal in microcontroller inputs (small mechanical noise can create jitter). Use a small RC filter (e.g., 10 kΩ + 10 nF) or oversample and average readings in firmware.
- Avoid exposing to dust/moisture; slide pots can wear or become noisy. If used in harsh environments, consider sealed alternatives.
- For audio applications, use logarithmic (audio) taper if smooth perceived volume control is needed; if only linear variants are available, use a logarithmic mapping in software or a simple audio taper network.
- Limit current through the pot: do not use it to switch large currents; keep within power rating to avoid overheating and wear.
- If mechanical backlash is an issue in position sensing, consider a detent or alternative position sensor (magnetic encoder, hall effect linear sensor).
4. Supported Platforms (OS)
The BSP for the TB8163P3 is generally ported for the following embedded environments:
- Linux (Yocto / Buildroot): The most common environment. The BSP usually consists of kernel patches and user-space utilities.
- Android: Requires specific
.ko driver modules and firmware placement in /vendor/etc/firmware.
- RTOS (Real-Time Operating Systems): For products like FreeRTOS, the BSP is provided as a static library and header files for integration.
2. Key Features
- Type: Open-loop or closed-loop VCM (verify per datasheet; many TB8163 variants support Hall element feedback)
- Actuation: Voice Coil Motor (Lorentz force)
- Stroke: Typically 150–300 µm (exact value depends on -BSP configuration)
- Operating Voltage: 2.3 V to 3.6 V (common for mobile VCMs)
- Current Consumption: <100 mA (peak during lens movement)
- Holding Current: 0 mA (spring return to infinity)
- Dimensions: Approx. 8.5 mm × 8.5 mm × 4.5 mm (standard for 8MP–64MP AF modules)
- Operating Temp: -20°C to +70°C
