Evaluates: MAX86140 and MAX86141 MAX86140/MAX86141 Evaluation System General Description Quick Start The MAX86140/MAX86141 Evaluation System (EVSYS) Required Equipment allows for the quick evaluation of the MAX86140 and MAX86140 EVSYS MAX86141 optical AFE for applications at various sites Data Acquisition EVSYS Micro-PCB on the body, particularly the wrist. Both MAX86140 and (MAXSensorBLEEK ) MAX86141 supports standard SPI compatible interface. MAX86140 EVSYS Sensor PCB MAX86140 consists of a single optical readout channels, (MAX86140OSBEK ) while MAX86141 has two optical readout channels that MAX86141 EVSYS Sensor PCB operate simultaneously. The EVSYS allows flexible (MAX86141OSBEK ) configurations to optimize measurement signal quality Flex cable at minimal power consumption. The EVSYS helps the USB-C cable user quickly learn about how to configure and use the MAX86140 EVSYS GUI Software MAX86140 and MAX86141. MAX86140 Parser and User guide (included in The EVSYS consists of three boards. MAXSensor MAX86140GUISetupVxxx.ZIP) BLEEK is the main data acquisition board while Windows PC MAX86140OSBEK and MAX86141OSBEK are the Required Bluetooth LE Dongle CY5677 or CY5670 sensor daughter boards for MAX86140 and MAX86141 (not shipped with EVSYS) respectively. The EVSYS can be powered using the Optional LiPo Battery (LP-401230 suggested, not USB-C supply or LiPo Battery. shipped with EVSYS) The EVSYS comes with a MAX86140ENP+/MAX86141-ENP+ Note: If you do not already have one of the listed BLE dongles in a 24-bump wafer-level package (WLP). above, purchasing one is recommended. Procedure Features 1) The EVSYS is fully assembled and tested. Follow Quick Evaluation of the MAX86140/MAX86141 the steps below to verify board operation: Supports Optimization of Configurations Visit www.maximintegrated.com/evkit-software Facilitates Understanding MAX86140/MAX86141 to download the most recent version of the EVSYS Architecture and Solution Strategy software, MAX86140GUISetupVxxx Web.ZIP.
