The ESP32-Cam appears to have very severe operational voltage sensitivity…
I’m beginning to doubt the practicality of this device.
Here is my experience with trying to even mount this device on a simple prototype board.
For background, I’m just running the sample CameraWebServer example from the Arduino ESP32-Cam library.
Running from Adafruit FTDI directly connected with short leads. Supply Voltage 5.23V Current Draw 210mA → Camera running smoothly OK!
Running from Adafruit FTDI with short ProtoBoard pin jump & same short leads as before. Supply Voltage 5.24V Current Draw 170mA → Camera NOT running smoothly, running a bit but freezing often.
The voltage drop across the male / female pins on the ProtoBoard is essentially zero - With 5.3V on the FTDI being delivered to the female socket on the ProtoBoard as 5.3V
I also measured the resistance between the male/female VCC/GND pins at around 0.1 Ohm [including my measurement wires]
So I’m at a loss to know what is going on here - except to note that the ESP32-Cam [or the Camera] appears to be running at the outer limits of its voltage / current draw ability when running off 5V.
I would note that even running off my lab power supply @ 5V it again only manages to run smoothly with very short direct connections.
Is this everyone’s experience with the ESP32-Cam? If so I’m not sure this is a viable product.
I bought this to drive a robot car with vision, but I it can’t run - even in a simple ProtoBoard socket, then I can’t see this project continuing.
Any input, ideas, assistance here welcome.
