Hardware version from Banggood STC15W408AS 2019

[aleksey-ru52]

hello everyone i'd like to share some info and schematics for this "new" pcb/kit

it will not work correctly with existed hw because of shared pins for S1/RM and S2/GM, i cut button's wires and solder it to unused pins (P1_2 & P1_3 in my case), now it works as it should work

there is some additional changes in stc15.h to use P5_5 and changed settings in global.h should i post it to repo or just attach to this issue with instructions?
