i am going to connect stm32f103rct6 to ZM serial camera 320x240 pixel, 30fps. i see this camera probably easier than ov7670. i have used stm32f4 with ov7670 but it really hard and difficult, so i want use stm32f103 and serial camera which is programed easier. But i don't know whether i can get video from this camera. because i think speed of stm32f103 is not enough. Can you tell me should i do ZM camera with stm32f103, i really want to use stm32f103 instead of stm32f4. stm32f103 simpler and cheaper.

115200 baud is a bit optimistic to get 320x240 @ 30fps, which need something like 23Mbaud

Perhaps you can cite the documentation for the specific camera/model you are talking about?

This is camera which i use in my project https://www.adafruit.com/product/397

I am going to use this camera with stm32f103, tranfer video from camera to PC thoughout wifi. But i don't know isn't speed stm32f103 enough??? it just have 72Mhz, seem to be slowlyThis is camera's specificationTECHNICAL DETAILS

The 30fps describe the capabilities of the camera chip, the 115200bps the bitrate over the serial interface. No way to get VGA@30fps through a 115.2kbps interface. This is a limitation by design.

Well the F1 has more power than the Arduino, but you need to be realistic about the performance. You'll be able to take stills, streaming video at 30fps, not so much. If it transmits JPEG images, you'll need a library to decode that.
