STEVAL-IMEV Single-lead electrocardiogram (ECG) and body impedance evaluation board Description Data brief Features Provides full access to all HMD features through a graphical user interface (GUI)

1 STEVAL-IMEV Single-lead electrocardiogram (ECG) and body impedance evaluation board Description Data brief Features Provides full access to all HMD features through a graphical user interface (GUI) Utilizes the STMFCBT low power high performance -bit microcontroller powered by ARM Cortex -M The ESDALCL-SC provides ESD protection with very low capacitance debug test points to interact electrically with the ICs mounted on the board DB- patient simulator connector facilitate its use on the user s test bed Device firmware upgrade (DFU) procedure to easy upgrade the STM firmware RoHS compliant The STEVAL-IMEV is a product evaluation board designed around the new HMD diagnostic-quality analog front end for bio-electric sensors and bio-impedance measurements. The board is designed to demonstrate the performance of the HMD in a single-lead ECG system, such as automated external defibrillator (AED), portable ECG, fitness and heart rate monitoring. It hosts a -bit microcontroller from the STM family, which manages the SPI protocol of the HMD and USB communication to/from a PC. Any board can be used with dedicated PC software GUI to demonstrate all of the various configurations. May DocID Rev / For further information contact your local STMicroelectronics sales office.
