The number of GPIO pins on the ESP module can be expanded with a PWM Expander. We will use the PCA9685 that provides 16 more pins that can be used as PWM output. This way it becomes possible to control 16 dimmable LED's
The PCA9685 needs to be connected through the I2C interface. This chip is compatible with 3V3 and it can be connected to the ESP without levelshifters..
PCA9685 ESP-01 GND GND VCC VCC SDA GPIO 0 SCL GPIO 2
The device is listed in the device dropdown, but you don't have to select it. There's actually nothing to configure there and the logic will work without selecting this plugin. You can use the control web page to set PWM levels using http commands to ESP Easy.
