Sort Communication Module
The control core of every Accordion. Two I²C channels, UART, SPI, JTAG, fan control, and synchronized analogue sampling — software-defined.
Communication modules for the Accordion test system speak to embedded DUTs through I²C, UART, SPI, JTAG, and other standard protocols. The Accordion node hosts these communication modules natively. All bus channels follow the same Accordion channel model as every other module.
The catalog covers integrated bus controllers with multiple protocol channels and long-range I²C extensions for distributed test setups. For co-located DUTs, the integrated communication module handles bench and production test. Long-range I²C extends the same Accordion API to production lines and test cells with longer cable runs.
