How to use the ECG

Here’s some basic info on how to use the ECG functionality of your card10

Finger ECG

Your card10 comes with a number of fun things to play with

• 1 : Contact, negative ECG electrode
• 2 : Pluse oxymeter (can [potentially, if at some point supported by software] measure pulse and blood oxygen levels using an optical sensor)
• 3 : Contact, negative ECG electrode (again)
• 4 : Screw (also works as a negative electrode, see [8])

• 5 : COM (for bias)
• 6 : Contact, positive ECG electrode

• 7 : Pin for soldering/stitching an alternative electrode, if you don’t want to use (6)
• 8 : Plastic distancer, works as an isolation (see [4])

USB ECG

• see ECG Kit Assembly on how to solder your ECG cable
• NB: it DOES matter how you connect the kit via USB. if you get a lot of noise, try to turn the connection

Have fun experimenting with the ECG.
