The MAX86140/MAX86141 Evaluation System (EVSYS) allows for the quick evaluation of the MAX86140 and MAX86141 optical AFE for applications at various sites on the body, particularly the wrist. Both MAX86140 and MAX86141 supports standard SPI compatible interface. MAX86140 consists of a single optical readout channels, while MAX86141 has two optical readout channels that operate simultaneously. The EVSYS allows flexible configurations to optimize measurement signal quality at minimal power consumption. The EVSYS helps the user quickly learn about how to configure and use the MAX86140 and MAX86141.
The EVSYS consists of three boards. MAXSensor BLEEK# is the main data acquisition board while MAX86140OSBEK# and MAX86141OSBEK# are the sensor daughter boards for MAX86140 and MAX86141 respectively. The EVSYS can be powered using the USB-C supply or LiPo Battery.
The EVSYS comes with a MAX86140ENP+/MAX86141-ENP+ in a 24-bump wafer-level package (WLP).
