Universal Sensor Hub Raspberry Pi HAT
Budget: ₹750 – ₹1,250 INR
Hello,
I’m looking to develop a custom Raspberry Pi HAT that acts as a universal sensor and interface hub for high-end projects. The goal is to significantly reduce wiring complexity while supporting a wide range of sensors and peripherals. The board should integrate multiple protocols and interfaces natively to allow seamless plug-and-play development for makers, students, and advanced users.
The design should include support for digital, analog, and communication-based sensors. For analog signals, I’d like a high-resolution multi-channel ADC (at least 16-bit, with simultaneous sampling where possible). For digital I/O, the board should expand GPIO capability and include configurable pins for PWM generation and interrupt handling. Communication support should cover I²C, SPI, and UART, with multiple dedicated headers for each so several devices can be connected without multiplexing.
Power management is another key requirement. The board should regulate clean and stable power for sensors, with selectable voltage outputs (e.g., 3.3V, 5V, and optionally 12V) and adequate current supply. Protection features such as over-voltage, reverse polarity, and short-circuit safeguards should be integrated. It would also be useful to have onboard level shifting to ensure compatibility with sensors and devices of different logic levels.
Additional features I’d like to consider include onboard EEPROM for configuration storage, a real-time clock with backup battery, and expansion headers for future scalability. The layout should be compact but designed with accessibility in mind, with clearly labeled connectors and spacing that allows multiple sensors to be connected simultaneously without crowding.
The final product should make it possible for developers to connect a wide range of sensors quickly and reliably, while maintaining performance and stability even in complex projects.
