shimmer app Shimmer ExG Module for Easy ECG/EMG Data Gathering

The ECG (electrocardiography) component provides a five-wire, four-channel signal for measuring bipolar limb and any of the V1 – V6 chest placements. The same device also does two channel EMG (electromyography) using a common reference electrode.

Features from the product page:
-Software configurable right-leg drive for common-mode interference rejection
-Software configurable amplifier gain
-Software configurable data rate
-Respiration demodulation capability on-chip
-Lead-off detection capability on-chip
-Test signal on-chip for validation purposes
-EEPROM storage device enables expansion board detection and identification, as well as 2032 bytes of data storage available to user
