ECG Module impressions. Useless device

  • I already wrote about poor documentation(
    Now, I tested acquisition speed of the device.
    Maximum data rate(DisplayECG() - OFF, delay(5) - OFF) is 66Hz.
    And it could not be increased without changing onboard STM32 FW.
    This uC acts as BLACK BOX. No description, no source code.
    DisplayECG() - ON, delay(5) - OFF - 45Hz
    Any serious ECG measurements started with data rate at least 250Hz.

    Initially, I planned to use it with IR pulse sensor for Blood Pressure estimation. Obviously, with 15 mS accuracy it is impossible.
