producto funciona muy bien. También he pedido el caso claro para ello que se puede encontrar en 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
works as expected and pcb looks fine to me
Este es el producto que entregarán no el que muestran
good. 2 week deliveri
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
