16 Relay Trigger 12V LM2596 Power Control Module with Optocoupler Protection
A part of the review has been auto-translated.
product works great. I have also order the clear case for it which can be found at https://www.banggood.com/Transparent-Acrylic-Case-Protective-Housing-For-16-Channel-Relay-Module-p-1215076.html
Rispetto a quello a 8 relè questo non solo sono a 16 canali ma sono anche optoisolati il che li rende perfetti per applicazioni domotiche.
perfect 16 Relay Trigger 12V LM2596 Power Control Module with Optocoupler Protection

You can use a "PCA9685 16-Channel 12-bit PWM Servo Motor Driver I2C Module"to drive the 16-relay board. Very easy with the Adafruit_PWMServoDriver library! Use pwm.setPWM(PinNr, 0, 4096); to activate the relay and pwm.setPWM(PinNr, 4096, 0); to deactivate the relay! you can power the Servo motor driver module and the Arduino by the relay board, it has a 5v outlet!
cant test and try for now
good quality, has a jumper for reversing logic state
ok
