Lillypad Mp3 power supply options

Post by punky_brewster » Wed May 09, 2018 1:58 am

Hi,
I'm looking for a practical way (and cheap) to power my project using my lillypad mp3 board. Is it ok if i solder directly a usb cable on the + and - behind the JST lipo connector?. I will use a usb adaptator of 1.5/2 A 5V to plug it in the wall. I could have used the 3.3V sew tap since my power supply is regulated but my ground sew tap is already taken.

I also have another question on the lillypad mp3: is their an alternative to get the electrodes work with capacitive sensing/touch without having to connect them to ground? (like the touchboard does) Using the 5 outputs?

Thanks very much for the help!
Best,
Claire
