WIN – PIHAT – 8AI

WIN-PIHAT-8AI | 8-Channel High-Resolution Analog Input Board

The WIN-PIHAT-8AI is a high-precision industrial expansion board for the Raspberry Pi 4 and CM4. It is designed for professional data acquisition, enabling the Pi to accurately measure real-world signals from industrial sensors like pressure transducers, temperature probes, and flow meters.

Key Features

Dual Resolution ADC: Supports selectable 12-bit or 16-bit resolution, allowing users to balance speed and high-precision measurement.
Versatile Signal Support: Measures standard industrial ranges including 0-5V, 0-10V, and 4-20mA current loops.
Multi-Bus Communication: Interfaces with the Raspberry Pi via I2C (for 16-bit precision using ADS1115) or SPI (for 12-bit high-speed sampling using MCP3208).
Scalable Architecture: A compact (56mm x 85mm) population-based design that supports between 1 and 8 independent channels.
