Micro USB power input broken

[tapatrick]

@ALLOsupport @Allo

 

The micro usb input has broken off my Sparky SBC (it is not very strong and a slight twist has dislodged it). How can I now power my sparky from an alternative input.

 

Also what are the 2 pins that say BATT on the corner of the board. Is this for battery input? I can't find any documentation for this.

 

Thanks for any help.

solved it

 

Soldered new wires straight to the pins 1 and 5 on the board under the removed micro usb input.

would still like to know what are the 2 pins at the top corner that say BATT. Is this for battery input? I can't find any documentation for this.

These pins for connecting 3.7VLi batterry . Pin-1 is +ve , Pin-2 -s -ve. 

Can be powered by Lithium battery or DC Adaptor,  on-chip battery Charger supports charging.

Thank you for your swift reply. Is this battery input enough to power the whole board or one part of it? I thought it needed 5v2A or is this stepped down to 3.3v?

yes , 3.7v-3500mAh battery connecting to PMU, it will distributes power to all interfaces like HDMI , USB 3.0 , USB 2.0. Not to the add-on boards. backup depends  upon the Interfaces load connected on SBC.

Powering ON with Main DC in and Batt power act as power backup. 

power Adaptor  5v/2A is considering all the interfaces with full load ,  Start-up current required nearly 1.3 to 1.5A.

@ALLOsupport when these batteries are fully charged they are 4.2v. I presume this still okay to use them at this voltage?

yes, fully charge up to 4.2v.

@ALLOsupport So the main DC power source needs to be plugged in at the same time as the battery for startup? pardon my ignorance but what is the point of the battery in this case. I thought it could be used as an alternative to the DC 5v power, instead of the 5v input.

 

What benefits are there in running the battery?

 

Also "Pin-1 is +ve , Pin-2 -s -ve. "

Which is pin 1 and which is 2 as they are not indicated? Is the pin on the right with the triangle/arrow below it the +/positive/hot? (reading this with the battery pins on the top left of the board and BATT to left of pins)

@ALLOsupport hello. Are you able to help?

Pin 1 is the arrow/triangle marked one is +ve.

correction : Yes it will boot from the battery, booting time required more current to boot-up, 1..3 to 1.6A (depends upon the interfaces connected). battery pack should be able to feed this startup current without dropping the voltage.
