Building IOL Core4

The IOL Core4 is a compact 4-port IO-Link Master module for OEM integration. The idea: give hardware engineers a ready-made IO-Link frontend they can drop into their own designs, without having to deal with the MAX14819 analog circuitry themselves.

Each of the four ports is driven by a MAX14819 dual-channel transceiver, the host interface is SPI. The module is designed to fit directly into embedded systems, edge gateways, or custom PCBs. We also developed a carrier board for Raspberry Pi - for development or for Pi-based designs that require four ports.


The prototype is built and running. Communication stability looks solid: an initial long-run test passed nearly 200 million IO-Link messages without any issues. Electrical characterization (signal integrity, thermal behavior, power consumption under load) is still ongoing before we call it production-ready.


Next steps are completing the electrical tests and publishing the datasheet. Sample requests are welcome in the meantime.
