iQuest Low Frequency HATs
The iQuest Low Frequency HAT are precision-engineered 8-channel HATs designed for low-frequency analog signal acquisition on the Raspberry Pi platform. Built around two TI ADS1115 16-bit ADCs. These boards provides high-resolution data acquisition with a 0–5V input range—ideal for monitoring low-speed sensors, process parameters, and more.
Overview
iQuest Low-Frequency 0–5V 8-Channel ADC HAT for Raspberry Pi
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.
iQuest Low-Frequency 8-Channel 4–20mA Current Loop HAT for Raspberry Pi
The iQLF4A20M8C is a low-frequency, 8-channel ADC HAT designed for interfacing 4–20mA industrial sensors with the Raspberry Pi. Built around two ADS1115 16-bit ADCs and integrated precision 250Ω sense resistors, it converts industry-standard current loops into accurate voltage readings (1–5V), fully accessible over I²C.
Each ADS1115 is factory-mapped to a dedicated I²C address, enabling simple and scalable multi-channel data acquisition. The HAT is optimized for low-frequency applications such as industrial monitoring, SCADA integration, and environmental sensing, where reliability and precision are critical.
