Board Mods to use 'non-rechargable' 2032 coin battery
I'm considering modifying my board to be powered by a 2032 3V Lithium (non-rechargeable) battery.
The list of proposed board mods I've come up with would be:
0) Remove Li-Ion battery.
1) Inject hot glue into the usb connector to make it un-usable.
2) Remove the voltage regulator IC.
3) Jumper the input and output pins(pads) for the voltage regulator IC.
4) Attach 3V 2032 coin battery leads: "Positive" to V3V Pin 7 and "Negative" to VGND Pin 4.
??? Any feedback on the viability of these board mods being able to support powering the board from a 2032 3V coin batt...???
I would have wired in 'above' the voltage regulator IC if I could have found a 3.6 or 3.7V Lithium (non-rechargeable) coin battery - but no such luck. The product spec shows the Dropout Voltage of the regulator IC to be 250mA so 3.6 or 3.7V seems like it would have adequate margin for wiring in above the voltage regulator - if I could find a 3.6 or 3.7V Lithium coin battery....
