LiPo LIR2032 Rechargeable for Puck modification

Sun 2020.03.22

Puck landing page indicates: 'based on a normal CR2032 battery'

http://www.espruino.com/Puck.js

A standard (normal) Lithium Manganese Dioxide (LiMn02) is 3V nominal with a capaity of 210-230 mAh

Although much lower capacity, LiR2032 battery is 3.6 V battery, with typical capacity in 50-70 mAh range and may be charged 500+ times. (lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, lithium nickel cobalt aluminum oxide - range 3V2 - 3V9)

Note on schematic indicates Diode at D7
see lower left

with note 'allow LiPo 2032s to be used if diode in here'

Instruction indicate to cut trace: 'If you cut the trace and solder a diode in, that'll drop the voltage enough that you can use a LiPo.'

I've stared at layout and Puck itself and have located D7

https://github.com/espruino/EspruinoBoard/blob/master/Puck.js/pdf/puckjs_brd.pdf

but it isn't clear where the trace to cut is. It looks like the diode should be soldered between D7 - D8, but unsure of that also, but no trace between the two. (could it be on the back side of the board? - not easily accessible)

A diagram would really help here and maybe a photo if someone has made the mod.
