Plug'n Play almost!
Ideal IC board with minimal/no soldering for assembling your robot project's servo motors, LEDs etc. Compatible pin connections for popular micro servos, screw terminal for external power supply. Good luck, Dr Frankenstein!

Excellent price
Great quality and very versatile unit. For either servo or motor.. or both.

Does the job
Working as expected to control servos on points (turn-outs) on my model railway.

Power feed not connected
In common with some other reviewers, the latest one that I bought does not have a connection from the screw terminal positive. There does appear to be a transistor present, but it doesn't appear to function. On doing a little research, the mosfet that is normally used seems to be hard to hard to obtain as it is only available in China! This could explain the problems we are having.

External VCC does not work on these boards - No reverse polarity protection.
Disappointed to find out that the External Servo Power connector does not work. This means there is no reverse polarity protection on the V+ that you require to connect direct to.

Este dispositivo te permite controlar 16 servos de forma individual con tan solo una conexión serie I2C. Es facilísimo de utilizar y al ser un modelo muy popular vienen muchos ejemplos en la web. Lo puedes conectar a Arduino y usar las librerías que hay para él. Muy recomendable.

Tutti questi cloni hanno evidentemente una qualità dubbia... (e un prezzo molto contenuto!). Ho dovuto fare un piccolo cavallotto e poi funziona bene. Ho potuto usare la libreria Adafruit.
