Hello,
Found STM32 board inside STB. For what purpose this board?
According to Vyrian.com who sells the chip:
Description32-BIT, FLASH, 72MHz, RISC MICROCONTROLLER, PQFP48
From what I can figure from Google, this is a Microcontroller Chip Board with the powerful complex ARM Arduino based chip. The chip can be flashed with code to do just about anything, don't know exactly what this little board does on the Zgemma. The Microcontroller Board can be, or is connected to a USB Port to communicate to the chip, and I have seen this chip run a Vacuum Florescent Display with text.
As far as the Zgemma goes, I would guess this little board and chip help to Flash the box with different firmware by bringing in the data from the USB; and displaying it on the box and TV.
I could ask the factory, but I wouldn't know if I would get a very good answer. It is a powerful little do it all chip that doesn't cost much. It could even help run a dish motor, since it mentions motor control in the description below. Just have to see where the little traces go from it. [emoji5]
There's lots of info about this chip and board on Google, just search the chip ID number.
