I've attached some i2c stuff on my pi, so the pins: SDA,SCL, 5V, GND and PIN 18 (IR)
Now the Questions :
1. Does the HifiBerry block the usage any of these PINS?
2. Which Hifiberry DAC (DIY) should i buy? so that the "top" of the hifiberry has the pins to attach my own connector?
I would like to use the two CHINCH Outputs the HifiBerry provides.
