STMicroelectronics STEVAL-IME002V1

Overview

STEVAL-IME002V1 from STMicroelectronics is a multi-lead electrocardiogram (ECG) and body impedance demonstration board built around the HM301D diagnostic-grade analog front end, STM32F103CBT6 ARM® Cortex™-M3 microcontroller, and STG3692 quad SPDT switch. It supports 12-lead ECG acquisition, bio-impedance measurement, USB 2.0 full-speed communication, and on-board SWD/JTAG programming - enabling rapid evaluation of clinical-grade biosignal sensing systems.

For engineers reviewing the STEVAL-IME002V1 datasheet, STEVAL-IME002V1 pinout, STEVAL-IME002V1 application, or STEVAL-IME002V1 equivalent, this board serves as a complete reference platform for validating HM301D integration, evaluating SPI-managed ECG signal chains, assessing low-capacitance ESD protection (ESDALCL6-2SC6), and prototyping FDA-aligned patient monitoring firmware with DFU-upgradable STM32 firmware.

Technical Context

The board implements a dual-path biosignal architecture: one path routes up to three HM301D ICs for simultaneous 12-lead ECG and bio-impedance measurements, while the other uses the STM32F103CBT6 to manage SPI configuration, real-time data aggregation, and USB-to-PC streaming. The STG3692 switch enables dynamic lead reconfiguration without hardware changes.

Power is flexibly supplied via USB or external connector, with dedicated ESDALCL6-2SC6 devices (0.5 pF typical capacitance) protecting all ECG input channels. The board includes 37 test points, reset button, user LED/button, and a PC-based GUI for live waveform display and HM301D register control.

FAQ

Does STEVAL-IME002V1 support FDA 510(k) submission-ready designs?

No - it is a demonstration board, not a certified medical device. However, its HM301D AFE meets IEC 60601-2-51 requirements for ECG diagnostic equipment, and the board's layout, grounding, and ESD protection follow clinical-grade design practices used in Class IIa/IIb product development.

Can the board acquire raw ECG data at 1 kHz with 24-bit resolution?

Yes - the HM301D supports configurable sampling rates up to 2 kHz and outputs 24-bit ECG data over SPI; the STM32F103CBT6 buffers and streams it via USB at sustained 1 kHz with timestamped frames using the provided GUI firmware.

Is the graphical user interface (GUI) open-source or modifiable?

The GUI is Windows-based and distributed as a compiled executable with source code available under ST's license agreement (UM1724). Developers can modify firmware and adapt the GUI using ST's STM32CubeMX and TrueSTUDIO toolchain with documented HM301D register maps.

What is the maximum number of HM301D devices supported simultaneously on this board?

The board is designed to host up to three HM301D ICs - enabling full 12-lead ECG acquisition (with optional limb and chest leads) plus concurrent bio-impedance measurements across multiple electrode pairs using shared SPI and independent chip-select lines.
