STEVAL-IME002V1

STEVAL-IME002V1 Multi-lead electrocardiogram (ECG) and body impedance demonstration board Data brief Features ■ Two power supply options: USB connector and external power connector ■ Up to three HM301D: 12-lead ECG with bioimpedance measurement ■ STG3692 low voltage high bandwidth quad SPDT switch to manage the HM301D SPI ■ STM32F103CBT6: low power high performance 32-bit microcontroller powered by ARM® Cortex™-M3 ■ ESDALCL6-2SC6 provides ESD protection with very low capacitance ■ USB 2.0 full-speed connection ■ SWD/JTAG connector to program the MCU ■ 37 debug test points to interact electrically with the ICs mounted on the board ■ Reset button ■ User LED and button ■ Graphical user interface to manage HM301D and display data outputs ■ Device firmware upgrade (DFU) procedure for easy upgrade of the STM32 firmware ■ RoHS compliant Any board can be used with a dedicated PC graphical user interface to demonstrate each of the various configurations. Description The STEVAL-IME002V1 demonstration board is designed around the new HM301D diagnostic quality analog front end for bio-electric sensors and bio-impedance measurements. This board is designed to demonstrate the use of HM301D in electrocardiographs (or patient monitoring systems). It hosts a 32-bit microcontroller from the STM32 family which manages the SPI protocol of the HM301D, and the USB communication from/to the PC.
