Evaluates: MAX30001G
General Description
The MAX30001G evaluation kit (EV kit) provides a
single platform to evaluate the functionality and
features of the MAX30001G with Biopotential (ECG
and R-to-R) and Bioimpedance (BioZ) optimized for
Galvanic Skin Response (GSR) measurement capa-
bilities. The EV kit includes a MAX30001G evaluation
kit (EV kit) and a MAX32630FTHR Cortex-M4F micro-
controller for wearables. The MAX32630FTHR provides
power to the MAX30001G EV kit and contains the firm-
ware necessary to use the EV kit GUI program. The EV
kit ships with jumpers installed and supply voltages set to
typical operating values. Optional connections exist which
can be shunted to make use of different functionalities.
This EV kit is not a medical device.
