Just a heads up for anyone wiring up the PH2.1 using the current documentation.
From the documents:
You can see that:
1- The port is labeled as HMI but on the PH2.1 is actually labeled USB
2- The Buzzer is listed as pin 6 and the LED pin 5 which is the reverse of what has been delivered.
with the buzzer connected to pin 5.
And whats with the ridiculous length of the buzzer cable?
The only spot it fits is on top of the cube (I would think that would be really the wrong place to mount a buzzer).
