# Hardware Compatibility
### General Remark
Altrough a board looks similair, it can have major differences, eg.:
Although a board looks similar, it can have major differences, e.g.:
- Processor
- Ram (Size! & Type) -> this Project needs at least 4MB RAM!

This can cause different Power Consumption, Power Requirements, compatibility issues, etc.
Most manufacturers and sellers buy what's cheap today on the Asian markets. In the end, it looks like it is sometimes a trial and error approach which ESP32-CAM Module works reliable.

# 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 G cards working like a charm).
