Unlock the full potential of your Raspberry Pi projects with this all‑in‑one GPIO sensor expansion board. Designed for Raspberry Pi 4B, 3B+, 3B, 2B, and Zero models, it combines reliable power management and 8‑channel ADC functionality to simplify complex wiring and sensor integration.

Key Features

  • 8‑Channel ADC Input: Built‑in 8‑bit MCU offers eight analog input channels (A0–A7), enabling the Raspberry Pi to read analog sensors like potentiometers and photoresistors.
  • Wide Voltage Support: Onboard DC‑DC converter supports input from 5V–36V and outputs a steady 5V/3A power supply—enough for both Pi and peripherals.
  • Broad Compatibility: Supports all 40‑pin GPIO Raspberry Pi versions, including 4B, 3B+, 3B, 2B, and Zero.
  • Selectable Sensor Voltage: Easily toggle between 3.3V and 5V sensor operation using jumpers for flexible sensor compatibility.
  • Dual Power Input Options: Choose between a standard 5.5x2.1mm DC jack or screw terminal for convenient wiring setups.
