Jetson Nano - Control de Servos con PCA9685

[@simonvanrij6264]

Hi, is the power (Fuente de 5-6v) from a USB source or seperate adapter? and is this needed or could/should it work without? Thanks for the video :)

Hi, it is a separate power supply, without it it does not work since it is specifically for the servo to move. I use a power bank to which I connected a USB and the positive and negative terminals feed the PCA9685 diver. Do not feed it from the 5V of the Jetson nano, since the servo will demand too much current and the Jetson will shut down due to its safety system.

Hola, si quiero usar 2 pca9685 los puedo conectar al mismo pin scl de la jetson?

[@IN3DMEX2.0]

Hola! Cada driver pca9685 necesita sus propios pines. Conecta el primer módulo PCA9685 en: SCL en pin 5, SDA en pin 3. Conecta el segundo módulo PCA9685 en: SCL en pin 28, SDA en pin 27.
