Hello Everybody,
I am new to this fabulous project. So sorry for my eventually stupid questions
I am not elecronics expert But i was wondering why choosing STM32F103CBT6 and not  STM32F103Rx/STM32F103Vx  stm microcontrolers.
compared to STM32F103CBT6 . The STM32F103Rx/STM32F103Vx microcontroles offres much more GPIO I/O  (51 STM32F103Rx  and 80 for STM32F103Vx) allowing
to connect much more periphericals devices. If i am not wrong the BL motors are connected to the GPIO's I/O.
with the STM32F103Rx/STM32F103Vx we can just have the possibility to use Octo engines in addition the the Hexa ones.
More GPIO also means teh possiby to controls more devices (ex servos for cameras.....)

ok if there is no plan to use the STM32F103Rx/STM32F103Vx. Who we can use the CopterControl with Octo engines and more servo controled devices ? (like Camera, and other devices)


Thanks a lot for your help. ANd great job for all the contributors !

One reason (there may be others) certainly is the size of the chip. The VBT needs about 4x of the board area compared to the CBT. So the board would have to be much bigger.

This is already possible if you don't need the PWM inputs but connect your receiver via PPM or S-Bus. You can reconfigure some of the inputs as additional output and get up to 10 channel - enough for a octo + camera servos. You currently have to compile the firmware yourself to get this feature but it will be part of the next release that is still under testing.
