easyeda is ofcourse great. that is with exclusion of the user libraries. there is so much junk to sift through that it is impractical. Specifically, I am trying to design a decent bluetooth speaker setup (stereo) 2.1 with 8-10 18650 liion batteries and maybe sound actuated leds. also a battery power bank of 10 liion cells with monitoring/ protection, etc. with a port that i can connect & detach an optional solar panel charging circuit. referals or best would be if anyone had or knew of solid schematics/ footprints/ BOM, ur help is very much appreciated. please help.
