This document describes the design of an interface board for a medical kiosk that integrates different commercial off-the-shelf medical modules. The interface board combines measurement results from modules that measure vital signs like blood oxygen saturation, blood pressure, blood glucose, temperature, etc. and transfers the data via a kiosk application to cloud software. The interface board hardware design integrates modules using an ARM microcontroller. The firmware collects data from each module via drivers and sends it to a PC application through a graphical user interface. The design was tested by measuring various health parameters of a subject to validate the integrated system.
