Add on/off switch to AdaFruit v1.2 usb charger

Hello all.
Is there a way to add an on/off switch to the load output directly on the Adafruit USB LiIon/LiPoly charger v1.2?

I’m aiming to connect this charger to an ISD1820 voice recorder and player so that it can power the sound device as well as have a usb-recharge functionality for an attached LiPo battery.
As the ISD1820 also has two LEDs connected to it, the addition of an on/off switch somewhere in the circuit chain will allow me to turn the ISD1820 unit off when not in use.

Any assistance or advice would be greatly appreciated.

Hi Peter, Welcome to the forum,

Adding a switch on the load output of the charger shouldn’t be too hard but will require some soldering.
I found the schematic for the charger here.

I would probably try and make a proto-board to interface with the load and have a new connector to the voice recorder on that. Then connect the proto-board to the charger via the empty header pin terminals using some headers.
Adding a switch between the LOAD+ header pin terminal and new connector on the proto-board would then give you an on/off switch to the load.

Do you have a link to what you have? I’ve found this as both an IC and as a full PCB.
