There is an ESP32-S3 version of this camera breakout board, which is presumably what OP might have used for prototyping. The S3 variant easily justifies the slight additional cost, given that it's easily faster by an order of magnitude or greater, having SIMD and an FPU. https://github.com/espressif/esp-dl/tree/master/examples/fac...

Thanks for reading! > What are some use cases for FAST? The FAST feature detector is an algorithm for finding regions of an image that are visually distinctive, which can be used as a first step in motion tracking and SLAM (simultaneous localization and mapping) algorithms typically seen in XR, robotics, etc. > Is there TPU-like functionality in anything in this price range of chips yet? I think that in the case of the ESP32-S3, its SIMD instructions are designed to accelerate the inference of quantized AI models (see: https://github.com/espressif/esp-dl), and also some signal processing like FFTs. I guess you could call the SIMD instructions TPU-like, in the sense that the chip has specific instructions that facilitates ML inference (EE.VRELU.Sx performs the ReLU operation). Using these instructions will still take away CPU time where TP
