ESP32-Cam - Best Port Expander
Posted: Fri Mar 11, 2022 11:34 am
Hi
Can anyone suggest the best gpio port expander to use with an esp32-cam
i found 3 but not sure if there are any implications to use one or the other.

Wemos D1 Mini - I2C Sensor Interface Board - VEML6070
Software question:
As i am using both the camera and sd card the only useful pins left are the pins used for programming and debugging GPIO1 + GPIO3
Would using these for the i2c communication mean i would lose the ability to print to the serial monitor window ?
i am using the Arduino ide
Your help is appreciated.
regards
steve
