iQuest Low-Frequency 0–5V 8-Channel ADC HAT for Raspberry Pi

The iQLF5V8C is a precision-engineered 8-channel ADC HAT designed for low-frequency analog signal acquisition on the Raspberry Pi platform. Built around two TI ADS1115 16-bit ADCs, this board provides high-resolution data acquisition with a 05V input rangeideal for monitoring low-speed sensors, voltage signals, process parameters, and more.

This HAT seamlessly integrates into industrial, research, or DIY applications, offering plug-and-play functionality with I²C addresses 0x49 and 0x48, allowing both ADCs to coexist on the same bus. Each ADS1115 provides 4 single-ended or 2 differential inputs, giving you full access to 8 single-ended channels.
