The card10 is a portable ecg (besides many other things) and I was so happy to get my own recently.
I'm particularly interested in the MAX30001 for the ecg function, which is possible in two ways:
- directly suppling the lead with the finger of the opposing hand or
- with external usb-cable attached to cords.
The firmware gets regular updates fast improving the handling, in particular easy updates of code by soft reset in the most recent update.
