Evaluates: MAX30208 MAX30208 Evaluation System General Description Quick Start The MAX30208 evaluation system (EV system) provides a Required Equipment single platform to evaluate the MAX30208, a temperature Note: In the following sections, software-related items sensor with 0.1C accuracy. The EV system consists of are identified by bold text. Text in bold refers to items two boards connected through headers, a MAX32630FTHR directly from the install of EV system software. Text that microcontroller board, and the MAX30208 interface board. is bold and underlined refers to items from the Windows Also included with the EV system is a flex PCB that holds operating system. the MAX30208 IC. The MAX32630FTHR contains the MAX30208 Sensor Flex firmware necessary to use the PC GUI program and also MAX3020x interface board provides power to the MAX30208 interface board. The MAX32630FTHR MAX30208 interface board ships with jumpers preinstalled Micro-USB cable to allow quick evaluation of the MAX30208. Windows PC with USB port MicroSD card (optional) Features Lithium-ion battery (optional) Flexible PCB Design Low Thermal Mass Allows for Fast Response Time Procedure Sense Temperature Away from Extra Circuitry The EV system is tested and ships in three pieces: Easy to Reach Test Points MAX30208 Sensor Flex, MAX3020x interface board, and MAX32630FTHR. Fully Assembled and Tested Follow the steps below to verify board operation: Windows 7, 8, and 10-Compatible Software 1) Plug the MAX32630FTHR into the MAX3020x Inter- face Board.
