first thing first, sorry, if this is not the correct forum for it ( I would appreciate if indicated)
I recently received some LED lights + microcontroller & battery (savaged from a pair of cheap LED shoes) similar to the picture below.
In the PCB it is marked F22-A and the battery is labelled SANBAO.
Please, could somebody indicate if microcontroller is know, if it could be reprogrammed ... etc.
I would like to use for another project and as the core has already both microC, battery and is casted in resin (so no problems with water and other liquids...)
Thanks and best regards,
EDIT: Found another picture
