+# Hardware Compatibility
+
+See also https://github.com/jomjol/AI-on-the-edge-device/discussions/1732
+
+General Remark: similar "looking" Board can have major differences:
+
+- Processor
+- Ram (Size! & Type) -> this Project needs at least 4MB RAM!
+- Flashrom
+- Camera Modules
+- Onboard/External Antenna
+- Quality of Components
+- Manufacture Quality of the PCB and soldering
+- Different Components
+- "Clone" Components -> ESPxx
+- etc.
+
+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.
+
+Below you find some remarks and experiences from the community:

+# OV2640 - Camera
+
+The experience with the camera only is based on single modules. It is well possible, that this module had a damage overall and other modules of the same type will work. Give it a try and report to me!

+
+# 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).

+# 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/
