# Hardware Compatibility
## General Remark
Although a board looks similar, it can have major differences, e.g.:
- Processor

There seems to be a lot of "fake" chips, or maybe wrongly configured ESP32 Boards.
For AP MEMORY, all "real" APS**64**04\*3SQR chips should work.
For ESP PSRAM, all "real" PSRAM**64**\* should work.

# SD Cards
Due to the limited free available GPIOs (due to all the extensions needed like: camera, SD card, LED-flash, ...) the SD card is connected in 1-wire mode. There are some cards, that are compatible with the esp32cam module for unknown reasons.
It is observed, that smaller cards (up to 4 GB) tend to be more stable and larger cards have more problems. But quite some exceptions in the forums (4 GB cards not working, 16 GB cards working like a charm).

# Weak Wifi
The ESP32-CAM supports an external antenna. It requires some soldering skills but can improve the connection quality. See [https://randomnerdtutorials.com/esp32-cam-connect-external-antenna/](https://randomnerdtutorials.com/esp32-cam-connect-external-antenna/)
