anyone has a solution for connecting to power directly to the battery connector by usb?
I thought used a 3.7V zener diodes in parallel between the - and + USB power and a series resistor.
I've used LP3874. You'll need a fair bit of capacitance in order to transmit.
Nice !!!! How you connect?
I designed a PCB with a battery contact and a case to hold it in place. I've seen several people solder connections permanently to the phone.
it was just the power connect to a USB port and trasmition and another connection.
I don't understand this.
