Do you think it's better to use a Raspberry Pi with an external ADC, or any other suggestions?
@Petr Dvořák Do you think it's better to use a Raspberry Pi with an external ADC, or do you have any other suggestions?

Hi @Ben I'd prefer Raspberry Pi over STM32 for openCV because its much easier to leaverage upon prebuilt model or python examples codes, than spending countless hours. User community of OpenCV and Raspberry Pi much bigger than STM32. If you want lightweight code with highly accurate ADC then using STM32 will make a sense. Otherwise, the RPi has different variants(1GB, 2GB....8GB to handle heavy pre-trained model). Apart from this using RPi CAMERA Model-3 give you access
libcamera API, `Auto-...4 Replies
Using an external ADC is preferable. It will give you more accurate readings. I think some pi don't have built in ADC, there gpio just function as digital pin.

libcamera API, Auto-focus, face detection built-in and much more. The RPi accessories widely available at anywhere. I'll be using Raspberry Pi Camera Model 3 in this weeks Engineering Hour. Looking forward to see you on Sunday, 15:00 GMTWhat are the requirements for the conversion? How many bits do you need? What is the bandwidth? How many channels?
@Ben what did you end up doing?
