hardwiring a USB Boost

Post by leo_stuck » Wed Jun 18, 2014 1:02 am

i am using a USBBOOST to power my leostick & it's sensors. The enviroment in which it operates is
subject to rapid acceleration & sudden shocks, as a result occassionally there are interruptions to the power connection - very short in duration but enough to disconnect the sd card module & cause the whole thing to hang.
I would like to hard wire the usbboost to the VIN pins on the leo'. If i remove the socket on the usbB can I solder the wires to the 2 outside contacts? are the 2 middle contacts used at all ? (there appears to be components & tracks leading to them). Lastly can you see a problem if I use the 2 socket mounting holes to srew the usbB' to the board which everything else is mounted on?

Hi Leo,

That setup should be fine. The two middle connections (USB data lines) are connected on the USBBOOST in a way that signals to a connected iPhone or iPad that is can draw 500mA. The LeoStick doesn't pay any attention to them.

Regards,

Angus

You can also leave the socket in place and just solder wires to the two solder pads at the back of the socket. This is what I'd probably do.
