What is it?

AQEX qPIOLite is the most affordable way to add isolated inputs and relays to your Raspberry Pi.

Why did you make it?

Most Raspberry Pi IO modules are overpriced and oversized for simple tasks, as they offer more ports than required. We have designed Synapse Nexus Lite to eliminate the cost of unused capacity. By focusing on 2 opto-isolated inputs and 2 relay outputs, we created a compact and budget-friendly module. It provides professional-grade protection and control for projects where two channels are exactly enough.

What makes it special?

Optical isolation Optically isolated channels safeguard your Raspberry Pi from electrical noise and damage.

Wide input voltage range 3-45V range for level type inputs.

Versatile SPDT Relays Each relay features both Normally Open (NO) and Normally Closed (NC) contacts, letting you choose how to control your circuits.

Reliable connection Massive, soldered pin header for power and signal connection. Pogo pins are not reliable.

High quality IO connectors All IO connectors are high quality, vibration-resistant spring terminals.
