  • I’ve been thinking about making a portable power bank using this board alone by adding a female usb connector to the output and adjusting the D+ and D- pins with the extra resistors like in MintyBoost3. I was just wondering if the 600mA is enough for some of the modern devices or will it be a problem?? Please also advice if I’m missing something with the whole idea. Thanks

No public wish lists :(
