Use of "drop-in" PHYTEC SOMs also ensures interchangeable microprocessor core circuitry in the event of obsolescence of parts used on our SOMs. You no longer need to redesign your entire circuitry to accommodate new or obsolete parts. Instead, PHYTEC manages this at the level of the external pinout of our SOMs. We ensure continued availability of pin- and function-compatible modules, further minimizing your maintenance costs and risks.
