Simple conceptually:
Solder blob on prototype means either build another one, or change some code to use another pin for same function.
PA0 can have PA2 or PA3 substitute for it.
PA2 function => tim5_ch3 instead of PA0 => tim5_ch1, except:
PA2, PA3 are available as serial port, which is good to keep...good for debug...
Hmm...maybe I should build another one? nahhh, takes a day...
PA4 PA5 are for HV sense ADC input, HV current sense ADC input.
PA6 is ADC input to monitor VBUS voltage of power input USB port.
PA7 is extra it could be tim3_ch2 except tim3 is used for an overall function, can't sub for tim5.
PB0 PB1 PB2 are extra, but only have tim1 tim3 Alt functions available...
Soooo, there's no good change to make that I can keep unless it is to lose using PA2, PA3 as debug serial port.
There are 16 fewer pins compared to G30TH.
I guess I make a version of tim3_enable_tim1_tim2_tim5__tim1_shuts_down.py
using tim5_ch3 instead of tim5_ch1 for the 1st article, and
keep a version of tim3_enable_tim1_tim2_tim5__tim1_shuts_down.py the existing way for ongoing.
